Anti-corrosion coatings for cars. There are also some minor downsides.

Car body rust treatment has a long tradition in our country. At times Soviet Union when a car was purchased once and for all, motorists covered the bottom with tar and poured hot fuel oil over the thresholds. At the dawn of the market economy, second-hand foreign cars also sought to extend the life. Now the era of technological anti-corrosion mastics has come, allowing you to look at the relevance and effectiveness of "anti-corrosion" from a different angle.

The essence of applying a protective layer is to create hydrophobic coating on the elements of the body structure of the vehicle. Before answering the question, what is the best way to treat the bottom of the car from corrosion, it is worth noting that fundamental differences there is no new and old car in the methods of processing the bottom. The only difference is that the battered bottom needs to be brought to a new state, rust removed, and then the technologies are identical.

Since you need to think not only about , but also about protecting the body from rust, we list the main areas that usually need anti-corrosion treatment:

• Door racks.
• wheel arches.
• Spars.
• Thresholds.
• Bottom.

The industry produces a fairly wide range of anticorrosive agents. All of them are divided into two groups - materials based on synthetic resins or bitumen and based on wax. Each manufacturer offers its chips in the form of additives in the form of zinc, polymers, rubber or bronze.

To correctly understand what an anti-corrosion agent does for a car and which one is better in all this abundance, it is enough to know two things:

1. Hardening mastics are used for processing open body structural elements: the bottom and wheel arches.
2. Non-drying preparations for hidden cavities with lack of ventilation: thresholds and pillars.

The quality of anti-corrosion protection depends on the level of surface preparation and compliance with technological nuances. It's about the same as - don't expect any quality without a thorough start.

Some motorists prefer independent production mixtures, but often this ends in wasted time and money. Therefore, it is worth using factory autopreservatives, especially since there is no shortage as such, and their price is quite affordable.

Stop rust or the better to treat the bottom of a car from corrosion in garage conditions

Anticorrosive agents intended for processing external parts must meet several requirements:

• Withstand deformation phenomena in the body structure.
• Reliably protect metal from various aggressive substances.
• Ability to withstand mechanical impacts.
• Have a high degree of adhesion.
• Have good elasticity.

There are quite a lot of similar tools on the market, it makes no sense to disassemble each one. Therefore, we will consider some of the most popular, and therefore, effective ones.

When applied, the anticorrosive preservative forms a dense film. It is better to work with a brush, spreading two or three thin layers at intervals for drying for 30 minutes. This, of course, is not entirely perfect solution the question is, what is the best way to process the bottom passenger car from corrosion, but the price of a liter of the mixture is very attractive - 167 rubles.

The mastic does not dry out for a long time, but after that it turns into an elastic layer, which is not so easy to remove in pieces. It can be used not only in the processing of the bottom, but also thresholds and internal door frames. The only condition is that you do not need to make a thick layer, because at the slightest mechanical contact with a solid object, a large area of ​​\u200b\u200banticorrosive can fall off. Therefore, it is sufficient to comply and don't try to improve it.

The advantages of the drug include the ability to perfectly preserve areas affected by rust. The corrosion process is suspended due to the complete blocking of air access to the destruction site. This will allow you to forget about the problem for several years, but even small scratch able to restart the process.

As a result, Movil Zinc is a wonderful tool for curbing already begun corrosion and temporary protection of the car bottom. You should not expect a special effect from this composition, it is best for them to treat places that are not subjected to mechanical stress.

Body 930 by HB Body

Mastic is produced in a package different capacity, which makes its acquisition profitable for one-time use. The mixture is based on rubber, so it is quite viscous, which allows you to apply a thin layer of corrosion protection even with a brush. Although the Greek company is not famous for its quality materials, acid primer and Body 930 showed good results.

Drying, the mastic forms a hard coating that does not crack and copes well with mechanical stress from gravel or sand. When buying a can of this preservative, we can say that the question of which anti-corrosion agent is better for protecting a car is practically resolved. It remains to take into account several features of the drug and recommendations for its use:

• Excellent mask for , creating a qualitative barrier to oxidative processes.
• The only problem is that after two or three years the coating needs to be renewed due to the intense mechanical impact of crushed stone or gravel.
• To be absolutely sure that salts and water do not get to the metal, it is desirable to apply an additional layer on top of the mastic. If a crack appears on the main layer of anti-corrosion protection, then Movil will close it.

Liqui Moly Unterbodenschutz by Liqui Moly GmbH

One of the best body anticorrosives is a thixotropic mixture consisting of bitumen, solvents, synthetic resins and special inhibitors. The elastic coating is resistant to abrasion, and also has excellent soundproofing properties.

As the layer thickness increases, the layer resistance to abrasion and rust protection increases. Therefore, it is desirable to make at least two layers.

We will find out which anti-corrosion agent for a car body is better when processing internal cavities

The main feature of this type of anticorrosives is their oil base, which does not dry out. Such a preparation will always be in a liquid state, which makes it possible for it to fill all microcracks. Most formulations are made on a paraffin or wax base.

It is important to note that repeated processing with mixtures of the same composition will not give the desired result. For example, you cannot work with wax on wax or mastic on mastic, because the new solution will not get inside the existing coating, and corrosion will progress.

To understand the best way to treat the bottom of your car from corrosion, you need to remember a few important requirements that apply to anti-corrosion mixtures for hidden planes:

• Homogeneous composition structure and high degree adhesion.
• Anticorrosive should not destroy the paint on the car body.
• Avoid contact of moisture and electrolytes with body metal.
• Formation of an elastic film and careful filling of all microcracks.

The product is available in plastic containers and is a liquid composition that can be applied even with an ordinary sprayer. The processing procedure is not particularly difficult, as well as , therefore, within the power of a novice driver.

The coating easily withstands pressure washing, but is not able to withstand crushed stone and gravel. Mastic is absolutely neutral to rubber, therefore it is suitable for processing metal elements under glass and door seals. It is this quality that distinguishes this product from Movil in a glass bottle, the latter deprives the rubber of elasticity.

The main areas of application: the internal cavities of the wings and trunk, body structures under the seals and the floor inside the car. Experienced motorists actively use Movil-Zinc to protect painted and chrome-plated car parts. Even after three or four years, after removing the coating, chrome retains its luster.

Zinc BodySafe by Tectyl

The drug combines all the wonderful properties that exist in Movil and mastic. Produced in aerosol cans complete with all kinds of nozzles for comfortable work. The mixture has good fluidity, so you do not need to plentifully process the plane, otherwise you can waste anticorrosive.

If you have not yet decided which anti-corrosion agent to protect your car from rust is better, then this is the drug that you should pay attention to:

• The aerosol jet makes it possible to get into any bends and cavities.
• The coating resists peeling even with the development of under-film corrosion.
• The coating has a fairly solid structure, which allows you to do without additional processing for a year or two, and if the machine is equipped with mudguards, then it will last for 5-6 years.
• Possibility of processing the bottom of the car.

The manufacturer claims that the drug fits well even on areas corroded. But practice shows that it is better to first get rid of rye, carry out phosphating and car painting , and only after that apply a protective mixture. In turn, Tectyl experts recommend making a three-layer coating, which includes:

• The first layer is Tectyl Zins ML.
• The second layer is Tectyl BodySafe.
• The third layer is Tectyl 190.

Of course, such a processing scheme will be expensive, but reviews from motorists claim that the technology is worth the money. For drivers who prefer to do without mudguards, the craftsmen recommend treating the bottom of the thresholds with a layer of Body 930, and walking on top with Tektil.

Summary

In the case when a critical level of rust has formed in closed cavities, it is necessary to Apply Movil with a rust converter. If the car is new, then any of the listed drugs will do.

In our harsh climatic conditions for the bottom, the optimal coating would be Body 930 plus Movil in glass containers or Tectyl Zinc BodySafe. The latter anticorrosive is preferable, but more expensive. Tektil is also effective when working with internal cavities, but Movil will cost less, which, moreover, can be found in aerosol cans with all kinds of additives.

The body is the part of the car that the owner worries about the most. And this is not surprising, because its replacement is an unreasonably expensive undertaking, it is easier to buy a new car. Accuracy on the road will protect you from external damage and scratches on the paintwork. As for the protection of metal from corrosion, anti-corrosion materials will help here. We will tell you more about what kind of anti-corrosion agent is needed for one or another part of the body, and about the most interesting proposals of manufacturers.

What should be a quality anticorrosive

More recently, the choice of a motorist in terms of protective autochemistry was limited to Movil, cannon fat and two or three types of liquid mastics. Today the market offers dozens of options for processing body parts. Despite this diversity, they are divided into anti-corrosion agents intended for the treatment of hidden and external surfaces.

The first meet the following requirements:

• high adhesive ability to smooth surfaces;
• the ability to create an elastic film after drying;
• chemical neutrality to metal, plastic and paint coatings;
• the possibility of penetration into the structure of the metal;
• fluidity sufficient to fill the slightest cracks;
• homogeneous structure;
• the ability to displace moisture and electrolytes from the surface.

These conditions are fully met by oil formulations. They have excellent penetrating power and are liquid for a long time, however, due to their low strength, they are not suitable for outdoor use. In addition, wax-based products are also presented in the distribution network. Like oil anticorrosive for cars, they are applied with, but they penetrate much weaker into the steel structure. The advantages of paraffin compositions are different. They fit equally well on paint and on, forming a protective film through which neither moisture nor chemicals penetrate.

A number of the requirements discussed above are supplemented by a few more points if the materials for anti-corrosion treatment of the car are used outside:

1. Mechanical strength sufficient to withstand the blows of gravel flying out from under the wheels and the abrasive effects of dust and sand;
2. The ability not to flake off and not crack under alternating loads and mechanical deformations of the body.

Modern anticorrosive agents extend the life of body parts and increase acoustic comfort in the cabin. At the same time, they will be able to fully express themselves only when the application technology provided by the manufacturer is observed.

Types of anticorrosives

Depending on the composition, funds for are divided into several types.

Bituminous mastics

Made on the basis of bituminous or synthetic resins, anticorrosive agents of this group cope with the conservation of body parts, slowing down corrosion processes and protecting treated surfaces from mechanical damage. To do this, corrosion inhibitors and dispersed non-ferrous metals are introduced into their composition. Mastics are applied in a thick layer - 250 - 400 microns, due to which they also perform a soundproof function.

Rubber and PVC materials

Mastic for the bottom of a car based on rubber or polyvinyl chloride is the most resistant and belongs to the deposited, since it is applied in a state heated to a high temperature. Materials of this class have very high adhesion and create an extremely strong, but due to the complexity of the technology, they are used in the factory.

liquid plastic

- This is an anti-corrosion paint based on acrylic compositions, which has anti-corrosion capabilities and, after drying, creates a durable protective film. Due to insufficient mechanical resistance, it is used more often to protect body parts such as sills, hidden cavities of arches, elements engine compartment etc.

Manufactured on the basis of bituminous and synthetic resins with the addition of mineral filler, shale mastic has high strength and resists abrasion factors. If you are looking for anticorrosive for the bottom, wheel arches or fenders, then you will not find the best material for self-treatment of these body parts.

Anti-corrosion primer

Anticorrosive primer refers to traditional anticorrosives conditionally. This material protects the metal from corrosion and is the lowest layer of the paintwork. At the same time, the restoration of the latter is possible only after priming with materials with anti-corrosion abilities.

Already by the name it is clear that this anticorrosive agent is durable and is intended to protect body elements from small pebbles and gravel flying out from under the wheels. With it, protect the lower parts of the wings and doors, bumpers, sills, spoilers, etc.

The best anti-corrosion products for cars

Even if outwardly everything is in order with the car, this does not mean at all that corrosion centers have not appeared somewhere under the paint. In order to keep the body in its original form for as long as possible, you should take care of its protection in advance. Not sure what to choose for processing body parts? We offer you a rating anti-corrosion agents, which, judging by the reviews of motorists, are the most effective and have the best combination of price and quality.

For external processing

There is a huge range of anticorrosive agents on the market to protect the exterior surfaces of cars, but car owners and service station masters often use the following brands.

BODY 930, BODY 950

BODY brand drugs have acceptable price and good performance properties, which earned popularity on Russian market. Mastic BODY 930 with a thick consistency, so that after drying it forms a strong elastic layer. Consumers note one drawback of this anticorrosive agent - low resistance to abrasion.

As for BODY 950, this agent is applied in the form of an aerosol, has increased hiding power and high penetrating power. It is devoid of the disadvantages of BODY 930 brand mastic, however, it has a higher cost.

One of the best, though not the cheapest material for protecting the bottom of a car. The anticorrosive agent made by German specialists proved to be the best in the process of many years of use. He has maximum margin strength against any impact - high humidity, ultraviolet radiation, aggressive substances, temperature changes and mechanical damage.

The drug of one of the most famous foreign manufacturers is fully responsible high status brand. Car owners note good adhesion, stable performance and elasticity throughout the entire service life. However, the disadvantages include insufficient mechanical strength of the material, which is why it is recommended to apply LIQUI MOLY UNTERBODEN-SCHUTZ in two layers.

Swedish-made anti-corrosion compound that can reliably protect the lower parts car body and does not require complete drying. The composition of the drug includes strong corrosion inhibitors, which, combined with thixotropic properties and excellent adhesion, allows you to create the most hermetic coatings. The disadvantages include perhaps a rather high cost, but this drawback is inherent in all anticorrosives of European manufacturers.

Russian-designed anticorrosive, not inferior to Western counterparts, is used to treat external body elements and as a protective layer on the inner surface of car arches. The disadvantage is a persistent smell, which will take more than 10 days to weather.

Product domestic production with a low price and good anti-corrosion and sound-proof properties. The disadvantages of polymer-composite mastic of this brand include low thermal stability.

Anticorrosive for hidden cavities

When choosing an anti-corrosion agent for hard-to-reach places preference is given to those materials that reliably protect and do not create difficulties during application.

It is considered one of the best tools for processing joints and welds. The rubber filler makes it possible to create an extremely strong, elastic film that copes with protection from moisture and electrolytes. However, consumers note some features Hi-Gear usage- the need for careful surface preparation and application of the agent in two layers.

Movil

Anticorrosive, known since the times of the USSR, has excellent penetrating abilities and after drying forms a resistant wax coating. There are several “movils” that differ in composition, among which they choose those that dry longer. As practice shows, they provide maximum protection and durability.

Canadian-made anti-corrosion composition, which, due to its high fluidity, is universal. low price and good penetrating ability determine the popularity of this tool among car owners. At the same time, it also has disadvantages - increased sensitivity to the purity of the base and too long stay in the liquid phase.

Like Rust Stop, it is used for processing outdoor and hidden surfaces. In addition to good anti-corrosion properties, it also has excellent sound insulation abilities. It is better to entrust the processing with this tool to professionals, since low fluidity requires special equipment and skills. The disadvantages of Noxudol 1600 include drying time (more than 3 days) and the need for additional protection of electrical wiring.

No matter how high-quality the vehicle body is, over time the material will corrode. At the same time, various small mechanical damage, exposure to moisture and other processes only contribute to the development of rust.

That is why many car owners use anticorrosive. About why such funds are needed, as well as the better to process the bottom of the car, we will talk now.

Among the reasons why people use anti-corrosion materials for cars are:

• increase in service life individual elements vehicle;
• increase in soundproofing properties;
• financial savings (since the cost of such a composition is an order of magnitude lower than carrying out body repairs).

Main varieties

When choosing an anticorrosive agent for a car, it is worth understanding that today there are several varieties of such substances. Among the most common of them are:

• bituminous. They are made from special bituminous or synthetic resins. Similar substances are preserved body element s, due to which corrosion develops much more slowly. To achieve this effect, special non-ferrous metals are added to the composition. The mastic must be applied in a sufficiently thick layer, which is 250-400 microns. At the same time, the material also increases the soundproofing properties of the car;
• rubber and polyvinyl chloride. Such substances are great for the bottom. They are highly durable. Able to tolerate almost any temperature. Also pleased with their high adhesion (the ability to stick to various surfaces). At the same time, applying them is quite difficult; this requires special equipment and skills;
• plastic. Liquid plastic anti-corrosion paints are based on acrylic compositions. When dried, the substance forms a resistant film that will well protect any body elements, including the engine compartment;
• shale. For production, bituminous and synthetic resins are used, while the composition also contains a natural filler. The strength is quite high, in addition, the film is practically not erased due to mechanical stress, which makes it a good option for the bottom and wheel arches;
• traditional. Another name is anti-corrosion primer. Used as the bottom layer of paintwork;
• anti-gravel. With the help of such a substance, you can protect the body from small pebbles and sand that flies out from under the wheels while driving. Using an anti-gravel coating, you can prevent the occurrence of chips and scratches on various body elements.

Basic requirements for compositions

If you do not know which anti-corrosion agent for a car is better, then you should pay special attention to the parameters of such compositions.

It is important that the means for treating external surfaces are different:

• good resistance to electrolytes;
• excellent indicators of adhesion;
• elasticity;
• ability to withstand mechanical influences.

In addition, it is desirable that the material does not crack or peel off after drying. In the case of processing hidden surfaces (bottoms), then it is necessary that the substance be sticky, with the same structure, elastic, well fill all microcracks and other damaged places that cannot be seen with the naked eye, and also have increased resistance to various influences.

The best anti-corrosion coating

Because the modern market crowded various models, then choose suitable option not so easy, because each manufacturer claims that it is his product that is of the highest quality.

That is why we have prepared a small one for you, which will help you decide on the best remedy for each specific case.

DINITROL

Swedish-made anticorrosive has been widely popular in our country for more than one year. The composition is quite expensive, but, at the same time, it is distinguished by its increased effectiveness.

In addition, a large assortment is also pleasing - the brand produces special substances for finishing individual elements of the vehicle (, engine, body element, interior floor, etc.).

Substance is great for self application. If you want to save some money, you should buy a liquid product, but you will need a compressor.

PINGO STEIN SCHLAS-SCHUTZ

It is difficult to find such a high-quality tool for protecting the bottom of the car. German anti-corrosion materials are famous for their reliability and durability.

The substance perfectly resists various influences, including humidity, ultraviolet radiation, temperature changes, mechanical stress, etc.

Movil

There are a couple of varieties, but it is best to buy formulations that dry for a long time. Can be used over other protective agents. Pleasant and pleasant smell of the composition.

Waxoyl anti-corrosion agent

The Swiss tool is suitable for the treatment of hidden surfaces. Of the advantages here it is worth highlighting:

• elasticity;
• frost resistance;
• low consumption (one liter is enough to protect the bottom of a conventional vehicle).

HB BODY

This very popular product is produced in Greece. Basically, the brand is aimed at the production of professional compositions for auto repair shops, but the line also includes anticorrosive agents for independent use.

The most popular option is the HB BODY 930 model, made on a rubber basis. At the same time, the composition also increases the soundproofing properties of the machine.

After application, the substance remains very elastic, thanks to which it protects the bottom and wheel arches from mechanical stress.

Pleases with a good combination of price and quality of goods from the HB BODY brand. At the same time, before applying it, you need to carefully read the instructions and properly prepare the work surface. The smell is not very pleasant, but after the polymerization process is completed, it will disappear.

Anticorrosive SUPRA-SHIELD

This option is perfect for those who want to save money. For only 200 rubles, you will receive a whole liter of protective composition, which includes corrosion inhibitors and water-displacing agents.

It should be noted that the product can be applied to wet surfaces, as well as under any temperature conditions.

The liquid texture allows the anticorrosive agent to penetrate into any elements (including plastic ones), preventing further development corrosion.

The warranty for one-time processing is three years. At the same time, the application of the substance requires a minimum of time. According to reviews, this anti-corrosion agent is the best choice for treating welds.

The disadvantage is an unpleasant pungent odor, as well as a long runoff of the substance from the surface of the vehicle.

Cordon

Another one domestic model which is great for car exterior trim. In terms of quality, this anticorrosive can be compared with the most popular European counterparts.

But a strong and pungent smell will accompany the car for another 10 days, no less.

Anti-corrosion agent Noxudol 1600

The universal composition is suitable for both hidden and external surfaces. Possesses both anticorrosive, and sound-proof characteristics. Due to low turnover, it is better to entrust the processing to experienced specialists, but you can try to do everything yourself.

The disadvantage is that it takes as much as 3 days for complete drying. It is also necessary to additionally protect the electrical wiring.

TECTYL

The American substance is suitable for use in severe weather conditions. The line is quite wide, including sprays and bituminous compositions.

Basically, they buy the Tectyl body safe composition, which contains zinc. This allows you to achieve increased protection of auto elements, regardless of the external environment.

The release of the composition takes place at a plant in Russia, however, its cost remains quite high. If you want to save some money, you can buy the substance in a jar, but you need a compressor to apply it.

Before surface treatment, the car must be dried. But all this is worth the money and effort spent - the reliability and durability of TECTYL is confirmed by the opinion of both professionals and car owners.

KROWN

This anticorrosive is made on an oil basis. It is worth noting the rather delicate effect of the composition, so that the paint layer remains intact. In addition, the water-displacing properties of KROWN are also pleasing (you can apply the composition after visiting the sink, you do not need to wait for the machine to dry).

The KROWN40 is suitable for machining rusty parts. In particular, it can be used to eliminate corrosion from the bottom, wheel arches, and hard-to-reach places. Working with spray cans is quite convenient, which is an additional plus.

Applying the substance will not take you much time - with washing everything will take no more than two hours. To achieve maximum body protection, the procedure should be repeated every year, especially for those vehicles that are used in an aggressive environment.

A few last words

If you want to prolong the life of your machine, as well as protect it from the effects of rust, you should use special anti-corrosion agents. The choice of agent depends on a number of factors, including the condition of the vehicle, the place of processing, the availability of special equipment, etc.

The modern market offers users a fairly wide range of such substances, while you can choose both domestic and imported high-quality formulations.

In any case, before using the substance, you should carefully read the instructions for use. Only compliance with all manufacturer's recommendations can guarantee effective protection of the main elements of the vehicle.

During the operation of the car, many of its metal parts are exposed to the negative effects of the environment, causing corrosive processes. Due to moisture, technical fluids on the roads, as well as anti-icing agents, it deteriorates appearance car, get worse specifications its important nodes. Today we will tell you about the special treatment of machine parts to protect them from negative influences.

1 How and by what means is the anti-corrosion treatment of a car performed?

Anti-corrosion treatment of the machine can be carried out using various means. All of them can be conditionally divided into those intended for processing external surfaces and internal cavities of the machine. Wheel arches and the bottom of the car are most susceptible to corrosion processes and damage from stones and sand, so anti-corrosion compounds must be applied to these surfaces in a thick layer. To protect them, it is customary to use special mastics made using bituminous resins, rubber compounds and polymers. Such products not only protect the vehicle, but also reduce the noise level in the cabin when driving.

The treatment of wheel arches and the bottom is carried out with sprayers or brushes, or with the use of specialized equipment. Due to the thick consistency of mastics, it is customary to dilute them with solvents before use, which evaporate after drying. It is customary to treat surfaces in need of protection with prepared mastic several times, applying each subsequent layer after the previous one has completely dried.

Means for protecting internal cavities differ more liquid consistency. They have good penetrating power, good moisture repellency and can neutralize rust. Such preparations are made on the basis of oil and wax components. For their application, a compressor and a special gun for anticorrosive are used.

For the application of special coatings, car owners usually turn to specialists. It must be understood that turning to a specialized station Maintenance, you can be sure that the work will be carried out by a professional who can select the best anti-corrosion agent and apply it correctly. In the arsenal of specialists there are expensive tools and equipment with which the masters will be able to perform the required application work. anti-corrosion coating as soon as possible. But the cost of professional services is quite high. It must be remembered that car services use only their own materials, which are characterized by high cost, which further increases the cost of processing.

If you want and have the time, you can do everything yourself. Do-it-yourself treatment of a machine from corrosion has its own positive sides. You save a lot, since you only have to spend money on the anti-corrosion composition itself. The process of applying protective substances can hardly be called very laborious or dangerous. All modern materials have low toxicity, and with minimal skill they can be easily applied to the desired surface.

We recommend using preparations in cartridges in which the protective agent is under pressure. Spray cans have special devices for processing even the most hard-to-reach parts and cavities. However, the quality of the processing of the body, doors and other elements of the vehicle will depend entirely on you. You will have to spend a lot of time working with specialized substances, and no one will guarantee that you can provide decent protection for your car on your own.

2 The choice of anticorrosive - different means for different purposes

When self-processing the machine, it is very important to choose a high-quality and functional anti-gravel agent. Depending on the application and chemical composition all specialized substances on the market can be divided into several categories.

To fill hidden cavities, it is customary to use liquid anticorrosives. These are non-drying oil compositions that allow you to effectively fill any microcracks. Such substances retain their liquid state, therefore they can fill even newly formed cracks and defects, but they are not used on open surfaces.

Liquid protective agents also include paraffin-based substances that can be used to treat metal and painted surfaces. After drying, such compositions form protective film, which protects the machined part from external influences. The disadvantages of all liquid substances include the relatively short period of protection they provide.

The most popular brands of liquid substances for processing vehicle components from the inside include:

• body;
• Movil;
• Mercasol;
• Noxudol 750.

To protect the outer surfaces of the car, mastics are used, which are usually divided into the following types according to their composition:

• bituminous rubber;
• rubber-bitumen;
• shale.

Bitumen-rubber mastics are commonly used for anti-corrosion treatment of the floor in the car, trunk and fender surfaces. Such compounds provide maximum protection for internal surfaces that are not subject to strong negative environmental influences. They can also be used to finish the outside of the car, but the protection will not last long.

Rubber bitumen compositions are different increased stability to temperature fluctuations. They can be used for processing both external and internal surfaces of the vehicle. The frozen anticorrosive layer is characterized by sufficient elasticity, retains its technical characteristics for a long time, does not crack or peel off.

Slate mastics are usually used for exterior surfaces, they can be used to treat the underbody of a car, wheel arches or doors. After drying, slate anticorrosive forms a hard film on the surface, which effectively protects parts from external influences.

To protect the car body, you can use special anti-corrosion primers. These compounds are characterized by a dense consistency and high water resistance. Before application, the primer is mixed with an oxidizing agent, after which the product dries to form a very hard coating.

It is necessary to apply a primer on bare metal, cleaned of dirt and paint, and also pre-treated with degreasing preparations. Primers have excellent adhesion, so they can be an excellent basis for applying subsequent layers of anticorrosive.

3 Procedure for treating car parts with anti-corrosion agents

Like many other car maintenance work, self-treatment with anticorrosive begins with surface preparation. First, they should be thoroughly washed with special shampoos, and then dried to dryness. For drying hard-to-reach places, it is best to use special industrial hair dryers. The pedals of the car must be protected from getting mastic with newspapers or cellophane.

If the vehicle components have already undergone corrosive processes, then the surfaces must be cleaned of rust. To eliminate it, you can use sandpaper or special rust converters. After that, all cleaned places are covered with an anti-corrosion primer.

It is best to perform processing in the warm season or in a well-heated, specially equipped room. We recommend starting work with the trunk and the floor inside the cabin. It is easiest to apply mastic on these areas and it will be possible to immediately check the quality of fixing the composition on the surface. Special attention when performing work, pay attention to welds. They are the most susceptible to corrosion.

While the floor and trunk dry, you can start processing the bottom, and wheel arches better to do in last turn because you have to remove the wheels to do it. For safety reasons, work must be done in sequence. First, remove one wheel, apply mastic. Then put it in place, remove the next wheel, etc.

While the mastic dries, you can do the processing of doors. For these surfaces, it is better to use liquid formulations in spray cans, they are easy to use and dry fairly quickly. At the next stage, you can start re-treatment of dried surfaces. It usually takes about 3 hours for one layer of mastic to harden, and complete drying occurs within 24 hours.

After applying the second layer of mastic, all remaining internal surfaces can be coated with protective compounds: stiffeners, thresholds and other details. For these nodes, it is also recommended to use special means in cans.

At the final stage of work, you just have to carefully inspect the car, find all the smudges and remaining anticorrosive stains on the painted parts of the car. It is recommended to do this until completely dry. protective compounds so that contamination with aviation kerosene or white spirit can be removed. They effectively remove anti-corrosion, but do not harm the paintwork.

It is possible to install the removed protection, insulation and other parts only after the protective compounds have completely solidified. At right action It will take you from 2 to 4 days to fully process the vehicle.

X Do you still think that car diagnostics is difficult?

If you are reading these lines, then you have an interest in doing something yourself in the car and really save because you already know that:

• Service stations break a lot of money for simple computer diagnostics
• To find out the mistake you need to go to specialists
• Simple wrenches work in the services, but you can’t find a good specialist

And of course you are tired of throwing money away, and it’s out of the question to ride around the service station all the time, then you need a simple AUTO SCANNER ROADGID S6 Pro, which connects to any car and through a regular smartphone you will always find a problem, pay off the CHECK and not bad save!!!

We ourselves tested this scanner on different machines and he showed excellent results We now recommend it to EVERYONE! So that you don't get caught Chinese fake, we publish here a link to the official website of Autoscanner.
