The body is considered the most vulnerable part of the car, and many motorists sooner or later wonder how to remove rust from the car. To process traces of damage on the body, you must first understand their varieties. It is also useful to consider in detail the tools and popular means for removing rust on a car body. In addition to removing rust on a car body, you should also know how to protect the metal from further exposure to a harmful destructive environment.
Causes of rust
Several factors can be distinguished:
- Weak protection from external influences. Some manufacturers, and VAZ in particular, do not pay special attention additional processing of the most vulnerable metal surfaces. The same applies to cars that have been in operation for several years. Neglecting protection against metal damage, motorists are often faced with a situation where simply treating rust is no longer enough. All this leads to the fact that it is necessary to fight corrosion, resorting to more serious costs and labor-intensive work.
- Minor damage, scratches and other defects are the first culprits that the body begins to corrode corrosion. If you do not get rid of such shortcomings of the body in a timely manner, then later it will be possible to rely solely on the overhaul of the car.
- Rain, snow, ice, mud, chemicals used to process pavement And so on. All this, one way or another, negatively affects the body. As you can see, the vulnerabilities car body so many. And in order to save and protect the metal from complete destruction, it is necessary to deal with corrosion centers in a timely manner.
Types of rust damage
Corrosion manifests itself in different ways, and depending on this, an appropriate method is selected that will help get rid of its destructive effects. It is conditionally possible to distinguish the following types of body lesions:
Small spot of rust on the surface of the body. Such a defeat is the simplest, and if it is not started, then the body can be easily saved and protected from further destruction. In this case, a simple cleaning of the area of \u200b\u200bthe car body from rust and applying a protective layer of primer will help.
Multiple rusty spots - one of the most dangerous species corrosion, which indicates that a large area of \u200b\u200bthe body is affected. Sooner or later, such a symptom will turn into decay, and through corrosion will form in this place. Corrosion inside the paintwork manifests itself in the form of small blisters of paint without noticeable traces of rust. Such swollen points characterize corrosion that develops under a layer of paint and varnish.
Defeats open type characterized by the fact that rusted metal patches are visible on the surface of the body, which gradually peel off. this is a serious type of lesion, which, in a neglected state, may require a major body repair when it is already impossible to simply cover with putty.
through corrosion- the most terrible type of destruction, in which rust gradually eats away the metal, leaving behind unrecoverable areas that can only be replaced. Depending on the type of damage, certain measures are taken to restore the damaged area. First you need to understand the tools and materials that are necessary for this type of work.
Corrosion Control Tools
A set of equipment for the treatment of affected areas includes the following items:
- Sander. This is the most important tool, without which metal cleaning will be long and tedious. To free the affected area from traces of corrosion in garage conditions, not necessarily expensive professional machine. It will be enough to buy an ordinary household grinder of small sizes.
- Tools for manual stripping. This includes a metal brush and tools for fixing sandpaper. Manual cleaning is inevitable in those places where it will be difficult to stick a grinder.
- Nozzles for grinders. These can be cup-type brushes with bristles of varying stiffness. You may also need circles on which sandpaper is attached. Cleaning with these nozzles will be much faster and with less effort.
In addition to a set of tools, you need to prepare the following Consumables that will help get rid of corrosion:
- Rust converter. A tool that is popular today, with which you can cover up the affected area and localize corrosion. The converter is made by manufacturers based on an acid that reacts with rust, neutralizing its spread. Such a composition can be prepared independently at home, for which distilled water is mixed in equal proportions with citric acid, and a little baking soda is added to the composition. Treatment with such a remedy will not be as effective as a purchased remedy, however, with weak lesions, its use will be quite appropriate.
- Degreasers will be needed in order to get rid of plaque before applying a protective layer.
- Automotive putty is needed to repair dents and other defects by leveling the surface.
- An anti-corrosion primer will be needed to treat the area before applying the paintwork.
Rust removal sequence
Treatment of the damaged area is to remove rust to bare metal. To do this, using a grinding machine, you need to completely get rid of traces of corrosion. This should be done with care in order to minimize the removal of live metal. It is worth noting that corrosion on the body number, if it occurs, can only be cleaned by hand so as not to permanently damage it.
If the corrosion is penetrating, the defects must be repaired with fiberglass putty. Severely damaged points on the car body may need to be repaired with a metal patch of the appropriate thickness. Through corrosion can also be sealed with reinforcing mesh and putty.
If the rust has not eaten the body much, then the treatment comes down to light stripping to metal and leveling the surface with ordinary putty. In the event that the corrosion points do not have large depressions after cleaning, they can simply be primed and prepared for painting.
Another way to stop the corrosion of a VAZ car or another model is to treat it with a converter. This should only be done if the rust has not severely damaged the metal. To do this, corrosion points are treated with the agent and left until the reaction is completed. Further protection of the metal will be to stop decay. The converter partially stops the effect of corrosion, but should not be relied upon too much.
Corrosion Prevention
Corrosion protection is just as important as corrosion removal and should be done regularly. inflicted protective covering constantly exposed to aggressive environmental influences, therefore, it requires constant updating.
Before processing, you should examine the points on the body of a VAZ or other specific model which are most vulnerable to corrosion. Their protection must be ensured in the first place. So, the most vulnerable points on any body are:
- wheel arches;
- thresholds;
- bottom;
- cavities inside doors.
The protection of these areas is slightly different from each other. For example, the bottom is processed by one, but the doors and thresholds are processed by another. To stop harmful effect moisture, it is necessary to create a protective film not only on the specified body parts. Very useful and justified in terms of cost is the treatment of paintwork with wax polishes, which create a protective film on the surface. Regular polishing can not only prevent corrosion, but gives the car an attractive appearance.
Rust is one of the most common car troubles. Its appearance can be caused by high humidity, aggressive road reagents, temperature changes and other adverse factors. In any case, measures should be taken immediately to eliminate rust spots and stains. After all, they spread quickly and can cause irreparable damage to the body of the car.
Before removing rust from the car body, it is necessary to carry out a number of preparatory procedures. This is an indispensable measure that will ensure further efficiency in the work on the elimination of corrosion.
- car wash- includes a thorough elimination of dirt and dust both outside and inside the body. It is recommended to entrust this task to professionals who use equipment with a powerful jet pressure. Let's wash the car and simple method, but with the indispensable use of car shampoo.
- Car drying- passes in natural environment, or with the help of car fans. Just before drying, wipe all water drops well, as they can cause stains on the bodywork during the drying process.
- Body inspection- necessary to mark areas marked with rust, as well as chips and cracks on the surface. In addition, you will need to examine the bottom of the car, wheel arches, thresholds and all components of the car interior.
- Highlighting areas affected by rust with adhesive tape.
mechanical way
In order to get rid of rusty bugs mechanical method, a sandpaper or a metal brush is used. In this case, you should first use a coarse-grained skin, and then switch to a fine-grained one. You can remove rust dry or moisten the surface of the body with white spirit. Kerosene is fine too. However, this procedure is effective only with a small area of the affected areas of the body.
Mechanical rust removal
If corrosive bugs have just begun to spread through the bodywork, an anti-rust varnish is quite suitable. It is easy to apply and does not require thorough cleaning.
Important! The anti-corrosion agent is applied only to a thoroughly washed dry surface.
When a vast area of the surface of the car is damaged by rust, it is necessary to resort to the help of a grinder with discs in the kit or a drill.
It is highly undesirable to use discs that remove too thick a layer of metal. Otherwise, there is a risk of cleaning the surface to holes where it is not needed.
But if, nevertheless, after removing the rust, deep depressions remain on the body, there is a method to fix this - apply putty with fiberglass. Before using the product, remove the slightest traces of fat from the surface. And after the putty has hardened, you need to level it with a special sandpaper P80-P120.
Chemical method
If bugs have formed in hard-to-reach areas of the car, the question arises of how to effectively remove rust on the car body, despite the fact that it is impossible to use the mechanical method. Here come to the aid of corrosion converter reagents, presented in the form of a gel, aerosol or spray. Their active substance reacts with the oxidized material and forms an airtight film. These products are easy to use and not only eliminate existing rust, but also prevent its further spread.
Remember safety precautions - do not allow the chemically active composition of the product to come into contact with the skin. Most corrosion protection products should be handled in a well-ventilated area.
There are many rust modifiers on the market, but among motorists, such products as:
- Rust neutralizer VSN-1- quickly turns corrosion into a grayish substance and is easily removed with a rag;
- Orthophosphoric acid- is a part of many reagents-rust converters;
- Spray zinc- after removal of rust, it forms a layer of zinc in the form of a protective film on the previously affected area, which prevents the revival of the metal.
You can also prepare a rust converter with your own hands. You will need to combine water and citric acid in equal parts, and then add soda to them (½ tablespoon per liter of mixture). The solution should be applied to any soft cloth and applied to the area affected by corrosion.
The electrochemical method of getting rid of rust has a high efficiency. The technique involves exposure to corrosive areas with a solution and electric current. The set intended for this procedure includes:
- two solutions - to eliminate corrosion residues and greasy traces and to fix the protective film;
- connecting wire;
- two electrodes.
The treatment process takes no more than 3 minutes, but the result lasts up to 5 years. This method is sometimes used to eliminate minor damage car body rust.
Final stage of work
After removing rust from the car body, a degreasing agent must be applied to the treated areas. When the product dries, add required amount anti-corrosion primer. However, if after cleaning the surface of the car remains covered with factory primer, there is no need for this procedure.
Finished surface after rust
Primers are needed not only as a base for paint, but also in order to protect against the occurrence of re-corrosion. Primers are presented in three varieties - sealant, primer and epoxy primer.
To paint the body, you need to choose a color that completely matches its main one. To achieve the best result, it is recommended to choose the paint color in the car workshop according to the car passport and paint at least three layers.
Properly carried out procedure for removing rust on the car body and strict adherence to the algorithm of the required actions significantly increases the life of the further operation of the personal vehicle. In addition, these factors contribute to significant savings in time and money for the motorist.
Hi all! In this article, we will consider an interesting topic, how to remove rust and bugs from a car body.
It is the most common and common problem that motorists have to deal with when servicing a car. Corrosion damage to the body is very difficult to stop. To do this, it is necessary to perform a series of protective measures ensuring the safety of the body, than in the future to eliminate the damage.
The most common cause of body damage is small gravel flying out from under the wheels of oncoming or passing vehicles, as well as chemical reagents that are used to reduce icing on the roadway and sidewalks.
Motorists often ask the question: “How to remove rust from a car body?” I will try to briefly answer this question.
The process of removing corrosion from a car body consists of several stages:
- car washing, with the removal of dirt and dust on the car body;
- body drying;
- examination of the body for the presence of areas damaged by rust, chips and cracks in the paint with mandatory inspection wheel arches, sills, the bottom of the car and a thorough examination of the floor inside the car;
- places damaged by bugs must be highlighted with adhesive tape;
- preparing the body for rust removal;
- work to remove corrosion;
- additional processing of cleaned areas from rust;
- applying putty with sanding until a smooth surface is created;
- coloring of prepared areas.
Car wash
The process of washing a car is carried out manually or by means of mechanization, using special sprayers. Washing must be carried out outside and inside the body, as well as the engine and luggage compartments with simultaneous inspection of metal surfaces.
To increase the efficiency of the washing process, it is necessary to use car shampoos that provide a thorough, gentle cleaning of the body, prepare the body for necessary work. Car shampoo washes away dirt, salt and grease easily. Returns the natural shine of the surface, protects the paintwork. The product does not contain wax, does not remove polishes, does not leave stains and streaks. The composition of car shampoos does not contain phenols, formaldehyde preservatives and other toxic components.
For manual washing most widespread received car shampoos: Shine-Premium, Lux-Premium, Car-Wash, Biolux.
When using automatic washing at the stations, the car shampoo of the Koch Chemie series is widely used.
Drying car body
Drying of the car body can be carried out in natural conditions or with the help of fan heaters. After washing, the car should be wiped well, removing all drops of water, which, in the process of drying under the rays of the sun, can lead to the formation of spots on the surface of the body.
Inspection of the body, identification of areas with a damaged surface requires the immediate installation of protective covers to prevent the ingress of chemicals and paint during painting work.
Rust removal work
At long-term operation car, especially in a humid climate (and not only), “bugs” are formed on the body. How to remove the "bugs" from the car body?
There are two main methods used to treat metal to remove rust:
- mechanical;
- chemical.
The type of repair associated with cleaning bugs with a car with your own hands is usually carried out in a personal garage using a set of tools for car maintenance.
mechanical method
How to remove bugs on the body? For this, places damaged by rust are usually treated with sandpaper or a metal brush. The cleaning of the damaged area in the initial stage is carried out with a coarse-grained skin, with the transition to a fine-grained skin in the further processing process.
Sanding can be done dry or wet. In the "wet" method, the metal surface is moistened with kerosene or white spirit.
Video: how to remove a bug (a small rusty spot) on the roof of a car.
When using a metal brush for cleaning, care must be taken, as metal subject to corrosion is easily destroyed.
Rust can be removed from the car body with a grinder. For this, a type-setting grinding disc is suitable, with the help of which a layer of rust is removed and the damage site is finally cleaned to obtain a smooth surface without traces of rust, with fine-grained sandpaper.
Very good result gives application for cleaning sandblasting machine which combines high efficiency and helps prevent body damage. Rust removal with a sandblasting machine is carried out by cleaning the metal with an air jet with sand particles. This method allows for high-quality cleaning of places of damage from bugs.

Video: what tool can be used to remove corrosion on a car.
It should be noted that when using cleaning mechanisms, it is imperative to use protective goggles and gloves, observing safety regulations.
chemical method
At chemical method removal of corrosion from the car body, various rust converters are used. They are able to prevent the spread of corrosion in places of damage. Auto cosmetics companies offer a wide range of different products.
1. Among motorists, the composition “VCH-1 Rust Neutralizer” has gained wide popularity, after processing with which rust is converted into gray matter, which is easily removed with rags.
2. The most commonly used rust remover from a car body is orthophosphoric acid, which is part of many rust conversion preparations.
3. Recently, motorists have been using zinc spray, which forms on damaged place a protective film of zinc particles, thereby preventing the revitalization of the metal.
Retail stores offer a special Zinkor-Auto kit consisting of a solution for degreasing and rust removal, as well as a solution for forming a metal coating with a protective film of zinc particles.
When using the kit, the place of rust damage is processed, and then it is connected to the battery using electrodes and zinc particles form on the metal surface. During the electrochemical reaction, zinc particles cover the metal, forming a protective film.
Video: removal of rust and metal in a galvanic way using the Zinkor-auto kit.
Additional processing
After cleaning the body from rust, a degreasing surface composition is applied to the damage site and, after drying, another layer of anti-corrosion primer, but this is if the metal is clean. And if it happened that after cleaning the metal remained covered with factory primer, then there is no need for a primer.
Primers are used to protect the metal surface and ensure better adhesion of the applied substances. Primers are produced in three types:
- epoxy primer;
- primer or primer-leveler;
- sealant.
Puttying and body painting
A layer of putty is applied to the surface to be treated, which is processed with the help of a moisture-resistant skin, leveled to a flat surface. Putty can be applied in several layers, and each time leveled with sandpaper to give it a smooth surface. And the last step before is applying the primer.
Corrosion affects the metal parts of the machine, despite their age. A few adverse weather conditions and now the enamel is already peeling off, as rust forms in its place. The reason may be incorrectly applied paint, so this problem sooner or later overtakes every driver, and he is interested in how to eliminate corrosion on a car?
Of course, you can contact a specialist in a car service, they will remove rust and restore damaged enamel. But be prepared to pay a significant amount of money for such services.
If you are not ready to say goodbye to it and want to control the process yourself, then get down to business, and this article will help you with this.
Why corrosion occurs
The destruction of the metal occurs from the impact on it of adverse environmental factors.
Corrosion is a broader concept than rust, which can most likely be attributed to its variety. It arises not only from exposure to water, but also from the chemicals that are present in it.
In this regard, the bottom of the car and its body most often suffer from corrosion.
Corrosion happens dry and wet. If car parts are in a dry environment, such as a garage, and still faded, they need anti-corrosion treatment.
Dry corrosion is not so detrimental to the hull. But wet corrosion is much worse, the metal is covered with a layer of rust and grows regularly.
If the process has just begun, it is necessary to deal with it while it is in its infancy, because it will be much more difficult further.
If you park your car in a heated garage with just cold air in winter time days, in this embodiment, the risk of metal destruction increases in case of poor exhaust in the garage.
A sharp temperature drop contributes to the appearance of condensate on the metal, and rust begins to destroy.
Rust is most often formed in those who do not clean the bottom in the cold season. Such a procedure gives only a short-term effect, but the car needs regular care.
After another trip outside your garage, you need to clean the bottom again from sand and water. Continuous maintenance reduces the risk of corrosion.
Do not flatter yourself that only in the cold season suffers paintwork.
It is worth noting that in warm weather, asphalt and sand particles fly into it, in which case it is also necessary to take measures, then you do not have to think about which method to choose to remove rust.
Varieties of corrosion
Given the characteristics of damage and types of corrosion, it is possible to determine how to remove rust from a car body.
1. Cosmetic corrosion can occur in places where car accessories are in close contact with the body.
For example, lights, grille, moldings and more. Rust in these areas is removed at the very beginning, and in the end there is no serious damage.
But if nothing is done with it, then it will turn into the next type of corrosion.
2. Under-film corrosion occurs under the coating in the form of certain pockets of rust. They can grow not only deeper, but also expand, and if not reacted, then everything can turn into a more severe form of rust.
3. Through corrosion is considered the final stage of destruction, in which through holes are formed, and the metal itself is eventually easily pierced by a solid object.
4. Pitting precedes through corrosion, problems arise already in the depth of the metal, and then the problem grows in breadth.
5. Spotted corrosion covers a large area of the car body. Over time, it turns into a through with irreversible consequences of destruction.
Places where rust appears the most
Negligence leads to the emergence of an increasing number of foci of infection. However, no matter what efforts the motorist makes, corrosion can appear on the wings, bottom, and thresholds of the car.
Not so often corrosion appears inside and outside the surface of the hood and trunk. But even these areas can be affected if you leave the car outdoors during the cold season, during rains or under snow.
Parts that come into contact with the overlays are the most exposed areas that rust can hit.
The areas of the floor that are under the driver's seats and feet are least often cleaned. If minor signs of corrosion are visible in these areas, they must be removed.
You must always remind yourself that even dry corrosion, due to indifference and wasted time, develops into through.
Take immediate action so that it doesn't turn into a serious problem.
Treatment of car metal from rust in a garage
Before proceeding with the processing process, it is necessary to prepare thoroughly by purchasing necessary tools for work, as well as possible coating materials.
If you have an unlimited budget, then be sure to pay attention to the special chemistry designed for cars, as well as a grinder, and a sandblaster.
If you are not going to contact a car service every time with this issue, but will solve it yourself, then these tools will still come in handy.
The machine will speed up the whole process as a whole, while all the work will be done efficiently and without the application of special force.
Mindfulness and accuracy of movements - important factors In that work. In the future, the same machine can be used in the process of body repair, painting and it is not necessary to buy the most expensive model, the rest also do their job perfectly.
The sandblaster is very expensive purchase, but so necessary when working with corrosion. Such devices can be seen on service centers. The most expensive ones are additional features– Abrasive recirculation function.
Sand under pressure will scatter in all directions, so a site is needed that will be fenced off from the main room.
If your garage is a limited space, then for cleaning, you will have to use brushes and skins of various sizes, which significantly increases the time of work and the forces applied to it.
Rust treatment in garage conditions is impossible without the purchase of the following chemicals: degreaser, rust converter, putty, anti-corrosion primer.
What they should be considered below, and do not forget to buy a pair of gloves to protect yourself when working with these substances.
All methods of dealing with body rust
Before you start working with metal, it is necessary to detect corrosion. For work, it is better to choose a warm day to wash and dry the car.
When you determine the places affected by rust, study its penetration depth and then try to pick up one of existing methods its elimination.
1. Working with a sandblaster allows cleaning with penetration into all pores of the metal.
The surface remains the same both in thickness and structure. The smallest particles of sand carry out active bombardment of corrosion.
Rust is squeezed through by grains of sand and washed out by them.
2. Grinding machine. The rust coating is destroyed, cleaned simply to the metal, this method is the fastest and most effective.
The only negative that cannot be avoided during corrosion is that the thickness of the metal being processed decreases.
3. Grinding by hand is carried out using a metal brush or sandpaper, falling on the working surface.
Scotch brite and abrasive discs are also used in this method. This method can be considered the cheapest, while you will always get into difficult places.
This method also provides for the fact that the thickness of the metal will suffer with all this.
It is worth noting that in some cases it is even more advisable to apply mechanical cleaning and treat with chemicals. Rust converters are sprayed from a spray can or brush.
When the substance is applied, it is necessary to leave it for a while, and then rinse with water. The body must be dried at the end and applied with an anti-corrosion agent.
The body without protection is not left for for a long time. There are also indelible ones on the market. anti-corrosion agents. You can’t put paint on them, because it simply won’t stick to them.
By reacting with rust, a special structure is created that is easy to lay down on a metal surface.
Therefore, such products are best used in places where the treated surfaces are not visible, and which require additional painting.
Now you are guided by which method is right for you to remove rust, and then it is already worth moving on to the main stages of work.
Basic steps for surface cleaning
Having decided on the method of removing rust, you can proceed with the initial processing.
As a result of stripping, the surface should be smooth, clean and even. If the work is carried out with one spot, then the corrosion center should be cleaned a little more. This stage is very laborious, because the work is carried out with an ordinary sandpaper.
The next step will be degreasing the area, working with a rust converter and aggressive liquids so gloves are required.
After cleaning the surface from the transducer, apply a primer to the surface. If level differences are visible, then you can’t do without a surface spatula.
If corrosion has managed to destroy the body completely, then it is worth using fiberglass putty, which will allow you to close the holes.
If the holes are large, then without special set with fiberglass, epoxy resin is indispensable. The kit contains instructions on how to apply the coating.
Additional tips for removing corrosion from a machine:
1. For a comfortable grinding process by hand, it is recommended to moisten the skin with white spirit. The places to be processed are indicated with adhesive tape or a cardboard stencil is applied on top.
2. You can also make a rust converter on your own by dissolving 10 ml in 2 liters of water citric acid and 20 grams of soda. After applying this liquid, some of the rust should move away.
3. Dishwashing liquid can be used instead of a degreaser.
4. To choose the right color for your car, you can always use computer diagnostics provided by a specialist.
5. If small areas are to be restored, then you can purchase special paint pencils that dry quickly enough on the part.
Now you can always cope with corrosion and protect your car from environmental influences or fix what corrosion has done.
How to respond to peeling of enamel?
The reason can be not only corrosion, but also the deformation of some parts itself. The old enamel will not, but you can return it using the grinding method.
With peeling paint, we act in the same way as with corrosion.
Sanding papers are used for these works. At the first stage, for more effective removal of the paint layer, use coarse-grained skins, then you need to walk over the entire surface with fine-grained sandpaper.
Upon completion of the work, we get a smooth surface without stripes.
If you run your hand over the surface, there should be no transition, only then you can degrease the surface and cover it with wax for polishing.
Do all the above procedures and your car will be like new, ready for operation. But still try to pay attention to care and prevent the occurrence of corrosion.
Cleanliness and dryness are the main criteria for metal.
How to remove rust from a car body with your own hands? literally every third car owner thinks. Corrosion in the city is a terrible epidemic that mows down cars all the time.
After contact with water and air, all products based on iron (Fe) and its alloys (steel, cast iron) corrode. Corrosion itself is an electrochemical process. During corrosion from the anode (such as a car body), electrons are released by emission through the electrolyte (water with dissolved salts) to the cathode (any metal parts that accept electrons).
Every year humanity loses up to 30% of all metal structures due to corrosion. It is quite possible that artificial iron oxide is the only product that mankind has produced in the largest quantity in its history.
Corrosion and how to deal with it
Since oxidation is a natural process, mankind has not figured out how to deal with rust on a car as efficiently as possible. But in modern world the consumer society does not need it. To ensure high rates of industrial production and profit, enterprises make cars with planned aging of components. As a result, such machines cannot last more than 5–10 years, no matter under what ideal conditions they are operated. But older cars were made to last and are operated for 20-40 years, and for them the fight against corrosion is very important.
There are several answers to the answer, how to deal with rust on a car:
- barrier protection using paints and varnishes;
- tread protection - galvanized body (when it is not the metal of the body that rusts, but its coating);
- electrochemical protection (by changing the electrode potential, if there is direct current only a separate part is oxidized - the electrode, and not all cars).
It is important to emphasize that the latter method is the most expensive and is used in exceptional cases. More often it can be found on gas pipelines.
Galvanized protection
In order to successfully remove rust from a car body with your own hands, you must use special diluted acids and an abrasive tool (zero skin). Users order in special car services additional processing of the body of their cars with special mastics or even galvanize the body. However, any of these types of body protection are very expensive and make sense for expensive cars that want to protect against increased corrosion in the winter (our utilities use aggressive agents to remove snow and ice from the tracks). It is almost impossible to do the treatment at home.
Is it possible to remove a small rust by painting it over.
When a car owner is annoyed by rust on a car, do-it-yourself methods of fighting become instantly relevant. It is not necessary to have a perfect car, but no one wants rusty and with holes. Moreover, it is much easier to localize a process that has just begun than a heavily launched one.
Well, if the automaker is worried about reliable, combined protection of the body and other metal parts of the car, but what if not? Then everything falls on the shoulders of the owner.
slow down time
When thinking about how to stop body corrosion, most motorists agree that it is better to wash the car more often (at least once a week) and keep it in well-ventilated areas, garages. To prevent rust from starting its victorious march along the car body, it should not be allowed to mechanically damage it, that is, bumps, scratches, dents and other things.
It is desirable to stop the corrosion of the car body at the initial stage.
Since then it will be much more difficult to do this, because the rusted body element you will either have to change it completely, or deal with its complex and expensive restoration. To prevent corrosion of the car from spreading at a rapid pace, many car owners try to order anti-corrosion treatment of the bottom and other elements of the car body even at the stage of purchase. So you can delay the start of the process for several years.
The easiest way to remove rust from a car body is with a weakly concentrated alkaline acid, but some motorists prefer processing only with emery cloths or electrified tool wheels (with a small abrasive grit).
What processing methods does the car market offer
To remove rust from a car, specialized chemicals can also be used that convert iron oxide to iron tannate, a very stable substance. The disadvantage of this method is the inability to convert the entire oxide, most of it remains, which means that the corrosion process continues.
Also, the fight against corrosion is possible with the use of newfangled polymer-based primers that protect the metal from moisture, and hence from corrosion.
But the most popular among motorists is considered to be full or partial (the most dangerous places) galvanized. With it, rust can be removed from the car body reliably and for a long time. In addition, the practice of the same Germans or Japanese shows that a galvanized body will remain in 40 years perfect condition, no rust marks (examples: Audi 80, 100, Nissan Bluebird, Mazda 626). That is, car treatment with zinc or chromates is a fairly effective method that has proven its effectiveness in practice. If im processed even individual elements body, you can significantly slow down the aging of the car.
Where protection is most needed
Having bought an inexpensive rust modifier, they begin to process the most subject to corrosion places: thresholds, wings, bottom. First you need to carefully sand the place of rust, and then process it with a modifier. The treatment site will turn unnatural green color, which indicates the successful completion of the rust modification process. After 12 hours, you can start priming and painting the problem area. It is easier to process on the trunk lid or door surface than under the car, but it is there that most moisture is present, and the bottom rusts much earlier than the rest of the body parts.
To know how to remove rust from a car body, you need to understand at least a little chemistry. badly sanded trouble spot or painting over rust does not work. Yes, you will mask the rust, but the process will not stop and eventually the car will rot right under the paint. In order to have as little rust on the car body as possible, efforts are needed, and considerable ones.
It is necessary to carefully clean, dry and degrease the place where there was rust, apply a high-quality primer (preferably on a polymer basis) and only then paint.
Corrosion on new cars
Experienced car owners know that the thickness of the metal in modern machines has become much smaller than it used to be. Now budget car begins to corrode after 2 years of operation.
Now motorists have three main problems:
- rust removal;
- elimination of breakdowns of the chassis;
- adjustment and protection of the engine power supply system.
