Are used different types fender liner. Similar parts made of plastic are already considered classics, however widespread these days, it is liquid wheel arch liners (lockers) that are received.

The steel sheet from which the car body is made requires an aggressive environment. The car frame is constantly exposed to heavy loads and vibration. At the same time, the action of moisture, sand, dirt and saline solutions, which fall on the metal from the outside during the ride, is also added. Therefore, the protection of the body, which is provided by liquid fenders, becomes a necessity. If the car is not protected, after a year and a half, the first traces of rust will be visible.

Some motorists naively believe that if the unit was purchased in a store, then it has undergone anti-corrosion treatment, therefore, additional protective parts are not required. The rest, who have no illusions about the quality and durability of factory protection, cannot come to a consensus on the choice of plastic or liquid wheel arch liners. Everyone can make their choice.

Plastic wheel arch liners are made of low-pressure polyethylene, they are installed directly into the car arch, straightened in place and fastened with rivets (self-tapping screws) to the body. Plastic fenders are durable and less prone to wear. They can be installed without special equipment.

Their disadvantages include drilling additional holes in the car body. Fender liners are manufactured by enterprises for each car model, and the area that is protected by a plastic fender liner is limited by its size.

applied to the surface wheel arches- this makes the protection more reliable, especially the space between the car body and the fender liner. Special composition(liquid locker) is applied to the bottom of the body and the inner surface of the arches, thereby providing good anti-noise and anti-corrosion properties.

The advantages of these wheel arch liners include the fact that the use of a plastic mass reduces the noise of the wheels by half. There is no need for additional drilling of the body. The application area of ​​liquid fender liner is not limited. They are universal for all car models.

When liquid wheel arch liners are used in winter, motorist reviews indicate that snow can clog into arches and turn into ice when temperatures change, which is dangerous for suspensions. Applying a locker requires cleaning the arches from dirt, adhering to the application technology and special equipment (compressor and sprayer).

- it is a bituminous composition in a viscous form, to which rubber granules are added. They are common in most countries of the world and are considered universal. A similar version of protective parts can be found in any car model.

The question of what to choose, plastic or liquid wheel arch liners, should be answered - one cannot contradict the other. If possible, it is better to apply both technologies at once, such an output would be ideal. Elements of the car body also need additional protection through the installation of protective linings or the application of anti-gravel agents.

Many owners, wanting to protect their car from corrosion, cause irreparable damage to the body. Consider what protection of the wheel arches will increase the level of comfort in the cabin and will not provoke rusting of the body.

Ways

For most drivers, mudguards are rubber shields that are mounted behind the wheels near the bottom of the front fender and rear bumper. If we are talking about a car body, then it is customary to call a mudguard a metal casing that connects the side member, engine shield and wings in the bow (glass suspension strut- part of the mudguard). In the stern, the mudguard is the wheel niche of the body. About the protection of these body elements and there will be talk.

The car owner can choose from only 2 ways to protect the wheel arches:

• fender installation. The plastic casing is attached to the wings and the inner cavity of the mudguards;
• liquid protection. The arch is treated with a special anti-gravel material based on bituminous and anti-corrosion components. For application, a special spray gun is used. liquid mass, or brush. After drying, a dense, damping surface is formed on the body, which has noise and vibration insulation properties.

Soundproofing deserves special attention. Due to vibrations from driving over bumps and the rumble of rolling tires, mudguard cavities are quite vibration- and noise-laden areas. Water flying from under the wheels, mud and large stones, hitting the metal part body, resonate, which leads to the transfer of noise into the interior of the car. Good soundproofing protection of the wheel arches significantly increases the level of comfort.

Which is better

If we consider plastic fenders and liquid protection apart, then The best way difficult to choose. If there are factory places for attaching protection, as well as appropriate plastic products, it is better to give preference to fender liner. They are more durable in use. You won't need to drill into the bodywork to install the rubber mudguards, which is a huge benefit.

If there are no wings regular places for fastening, and the owner does not want to bother installing lockers without self-tapping screws, it is better to choose liquid sound insulation. In terms of the level of transmitted noise, these protection methods are approximately the same, but the disadvantage of liquid wheel arch liners is their fragility. Constant impacts of stones, dirt, moisture, temperature changes and vibrations of the body lead to the delamination of the material. As practice shows, even high-quality processing must be repeated every 2-3 years.

The best way is combined protection with preliminary sound insulation. After applying noise and vibration isolation, the cavity is treated with liquid mastic. And only then the liner is installed.

The choice of lockers, mastics, soundproofing

Guidelines when choosing fenders:

• thickness. Too thin products are damaged faster and more prone to deformation in the hot season;
• elasticity. Lockers are made of ABS or PP plastic. The latter option is more elastic, and therefore often more durable. But even with the same labeling, you can feel the difference between manufacturers. You should not buy products that are too hard, as the material will completely harden in the cold, which can cause cracking;
• the presence of stiffeners;
• holes for standard fasteners, if any.

The choice of manufacturers is huge (API, ASAM, SA, FLORIMEX, GORDON, KLOKKERHOLM, POLCAR, SAT and many others). You need to identify manufacturers that offer fender liner for your car model, and then ask other car owners for experience. One of the main factors, which, unfortunately, can only be checked during installation, is the coincidence of body moldings with the shape of the fender liner. This will allow you to become protected without distortions and tightly close all cavities.

Mastic, soundproof materials

Previously, we have already considered on top of which lockers can be installed. Dinitrol 479 can be used to form liquid fender liners. As a pre-treatment before installing lockers, you can use an anti-corrosion mastic with a noise-absorbing effect from APP, Terotex, Schwarz or other manufacturers.

As sheet insulation are used:

• base layer of vibration-absorbing composition with a thickness of 2 mm or more;
• soundproofing material.

There are a lot of varieties of material models now, however, as well as manufacturers (Shumoff, STP, Vikar, etc.). Therefore, when choosing, you should focus on the price, as well as the thickness of the final coating. Soundproofing "sandwich" should not interfere with the installation of lockers. It is advisable to buy material with an adhesive layer based on mastic, and not water-soluble adhesives.

Preparation, soundproofing

Protection of the arches begins with washing the inside of the mudguard and drying it thoroughly. Then the entire surface is degreased. Option for good soundproofing wheel arches:

• a vibration-absorbing layer is glued to the entire surface of the mudguard covered by the locker you bought (for example, Shumoff L3 or M3. It needs to be heated before pasting). Sheets are tightly rolled with a metal roller. At the same time, the regular anti-gravel coating does not need to be removed;
• mastic is applied on top with a brush or sprayer. If desired, you can put in 2-3 layers, but at the same time observe the interlayer drying of 10-15 minutes. at a temperature of +20ºС;
• plastic lockers are pasted over with noise-absorbing material (for example, Shumoff Germeton A15). Also at this stage, soundproofing sheets based on foamed rubber can be used (as an option - Shumoff Comfort 6).

Proper installation of lockers

Many vehicles have factory mounting locations for fender liner. Special plastic "bugs" are used as fasteners. The use of self-tapping screws is permissible when attaching lockers to plastic elements(decorative door sill, bumpers). At proper processing you can use self-tapping screws as fasteners at the bottom of the inner cavity of the mudguard.

Never use self-tapping screws to attach the fender liner to the wing edge. Moisture is trapped between the plastic casing and the wing. In the place where the metal is exposed, rusting will inevitably begin, which, moving up, will destroy the paintwork.

When self-tapping screws are indispensable

If another installation method is not possible, or holes have already been drilled in the wing before you, the metal must be protected. If there are no traces of rust at the site of the paintwork violation, prime the area with epoxy primer and paint with acrylic paint from a spray can. Places of rust must first be cleaned and treated with a rust converter. After drying, the inner cavity of the wing and the edge adjacent to the liner, treat with anti-corrosion mastic (for example, Movilho). Before screwing in the self-tapping screw, also soak it in the mastic.

Helpful Solutions

Often, protecting the wheel arches with fender liner can only do harm. Vibrations of a poorly fixed product damage the paintwork in the plane of contact with the wing. There are two ways to deal with this:

• the edge of the locker is trimmed, and a special seal is put on it. Soft rubber coating adheres tightly to the fender and does not scratch the paint;
• use of body sealant. It is applied in places where the plastic is attached to the body. Contributes to waterproofing, which is important for both paintwork and glued sound insulation. The sealant performs not only a waterproofing function, but also acts as an additional fastener. After drying, it retains elasticity, and therefore does not crack.

Each car has its own strengths and weak sides. And this is well known to every car owner who knows his car from A to Z. Lately, a very common problem in many cars (both foreign and domestic) is the rotting of the rear arches. Yes, this is their weakness, or in other words, a disease that needs to be treated in order to prevent further development.

The rear arches of the car are perfect place for the development and spread of corrosion. In order to prevent the car from rotting, you need to use liquid wheel arch liners, which you can apply on your own without asking for help from a service station.

Liquid fender liner is a special anti-corrosion material that serves to protect the wheel arches and is characterized by high resistance to sandblasting. It must be applied in several layers, and the thickness of one layer is 2-3 mm.

Thanks to the liquid fender liner, the wear resistance of the car is increased, the level of dirt in the glasses and the noise due to the wheels are reduced by up to 45-48%. Feature and the highlight of liquid fender liner is not just noise reflection, but its absorption.

The advantage of liquid fender liner

In addition to liquid fender liner, there are also plastic ones, but there are 4 reasons why liquid fender liner is preferred:

1. Plastic wheel arch liners require additional holes in the car to secure them;
2. When using plastic, ventilation is disturbed, which in turn leads to condensation;
3. Anti-corrosion coating does not provide 100% protection against our reagents;
4. When using liquid wheel arch liners, additional sound insulation is created.

How liquid fenders are made

Do-it-yourself liquid fender liner is not only simple, but also economical. If you still decide to make liquid fenders with your own hands, all that is needed is to adhere to the following algorithm of actions:

Most car owners who make liquid fenders with their own hands note that such a procedure should be repeated 1-2 times a year for an effective result. As a rule, the duration of such work does not exceed 2 days (depending on the weather and the place of work).

The bottom of the machine can be processed in the same way. The most important thing is to have a lift or a pit in the garage, and also be able to wash and dry the bottom of the car well.

In conclusion, I would like to talk in more detail about the advantages of liquid fender liner.

Unfortunately, the quality of roads in our country leaves much to be desired. At the same time, none of the expensive foreign cars is produced with the expectation of such extreme conditions operation. Problem premature wear rear arches is especially characteristic of cars Honda brands, but also other cars of domestic and foreign production often suffer from this disease. In this regard, drivers are trying different methods to protect undercarriage your car from intense wear. One of the ways of such protection is tuning, and, in particular, the installation of liquid fender liner.

Technically, these products are special materials based on rubber resins, wax and oxidized bitumen. Liquid fenders are reinforced with fiberglass or rubber granules. After drying, a very strong, elastic and wear-resistant film is obtained, which is able to absorb noise and withstand abrasives, whether it be sand, gravel, salt or dust.

Liquid wheel arch liners are most often supplied in spray cans, completely ready for use. This is very convenient, because when spraying the material, it will fill all the microcracks on the surface. Manufacturers do not recommend adding additional substances, as they may impair the adhesion and strength properties of liquid fender liner.

liquid fender liner

Is the game worth the candle? How does such a complex composition justify itself, and isn’t it better to use the usual fender liner made of plastic, polyethylene, ABC or fiberglass?” - these questions are of interest to most motorists who hear about liquid fender liner for the first time:

• during the installation of products, no areas of crevice corrosion are formed. There is no need for holes in the attachment points;
• excellent resistance to moisture, wind and sub-zero temperatures;
• ease of application;
• complete environmental safety;
• the ability to install on almost any car.

Application process

In addition to their main function, liquid wheel arch liners solve the problem of sound insulation. It is this property that often tips the scales in favor of these products. But in some cases without plastic fender liner not enough. If regular fenders close a hole or a niche in the body, then after applying liquid arches to the surface, they return to their place.

The only conditional disadvantage of the bay arches is that for effective protection the installation process must be strictly followed.

There are several compositions on the market, so choose suitable option sometimes it's problematic. Each type of fender liner has its own advantages and disadvantages, on which the scope of its application depends:

Choosing the Right Option

• bitumen pads. They have pronounced soundproofing properties, but do not resist low-frequency vibrations too well. Therefore, it is better to install them on the rear wheel arches, where the vibration frequency is highest;
• wax products. able to penetrate into hard-to-reach places. Due to their transparency, they are almost invisible. Suitable for any part of the body;
• oil-based fenders. Ideal for cars with high mileage, the bottom and body of which are very difficult to clean.

Even the highest quality substance cannot provide the desired effect without pre-training surface, so right choice is not a panacea - it must be accompanied by professional installation.

Each motorist can install liquid wheel arch liners on their own or entrust this procedure to specialists from the service center.

Do-it-yourself installation

The installation process should look like this:

1. The car drives onto a lift or a conventional jack. If mud flaps are installed, they must be removed.
2. The bottom of the machine is thoroughly washed, after which it is dried dry.
3. All brake mechanisms are closed with bags or rags, and the layer of applied anti-corrosion coating removed to iron.
4. A new layer of anti-corrosion coating is applied to the prepared surface by means of smooth movements with a brush, and after it dries, another layer containing bituminous mastic is applied.
5. The last, 3rd layer, contains rubber, and is applied immediately after the second has dried.
6. When the material hardens, the machine is collected in its original state.

Manufacturers claim trouble-free operation of products for 2-3 years. But motorists who have already made liquid fenders with their own hands recommend doing this every 2 years, preferably in dry air.

No comments

Some areas of the car are more susceptible to the harmful effects of harmful phenomena. outside world, than others. Among them - and wheel arches. It is on them that rust appears first. At the same time, this problem is relevant for both imported brands cars, as well as for domestic ones. Rotting and corrosion, which are often observed on the wheel arches of a car, are unfortunately quite common.

It should be remembered that corrosion appears due to the fact that the paintwork and anti-corrosion coating of the car has been damaged. Moisture instantly penetrates even into the smallest chips and cracks, where rust pockets form.

Moisture can get there not only due to deformation of the protective layer, but simply because of a long stay vehicle in a room with high humidity. It is very difficult to get rid of rust on a car later, especially if the situation is running. 'Cause it's best to take it all possible measures to prevent such a situation.

So, what properties of wheel arches provoke accelerated rusting? The answer is simple: they are in constant contact with pavement, and this is not always clean and smooth asphalt. It can be crushed stone, soil, dirt, water, etc. Of course, all the pebbles and small debris that fly out from under the wheels fall on the wheel arch and gradually destroy the layer anti-corrosion coating on her. And the constant contact of these parts of the car with moisture and dirt only exacerbates the process and accelerates the development of rust.

What you need to know about liquid fender liner

Liquid fender liner (or liquid locker) is a special type of anti-corrosion material that is used exclusively to protect wheel arches from moisture, rust and all kinds of mechanical stress. In the vast majority of cases, liquid wheel arch liners (liquid locker) are applied in several layers. Moreover, each of them is no more than 2-3 cm in thickness.

It should be noted that liquid fenders (liquid locker) significantly increase the wear resistance of the vehicle, significantly reduce the amount of dirt that accumulates in the glasses, and also reduce the noise level produced by the wheels of the car while driving by 45-50%.

It should be noted that we are talking not just about the reflection of noise, but about its absorption.

What is the advantage of using liquid fender liner for wheel arches

Liquid wheel arch liners (liquid locker) for cars are not the only product of their kind. There are several analogues that are also used to protect wheel arches from dirt, rust and mechanical impact. However, all leading experts in this industry advise motorists to give preference to liquid wheel arch liners.

Liquid fender liner for car wheel arches

Here are just a few of the main advantages that distinguish liquid fender liner (or liquid locker) from all their counterparts:

• do not require additional holes in the wheel arches in order to be attached to them. Thus, you do not need to violate the integrity of the arches and spend extra time and effort on creating these holes;
• when using any other coatings along the surface of the wheel arches, ventilation is completely disrupted, which, in turn, can lead to the formation of condensate. And this is a direct path to rust;
• no other protective material provides such quality protection wheel arches from all road "surprises". When spring comes and the snow melts, a layer of salt appears on the roads, which was poured into winter period in order to prevent accidents due to ice. This salt, when it hits the wheel arches, almost instantly destroys the anti-corrosion layer on them;
• no type of coating that is applied to the wheel arches of a car creates a soundproofing effect, and therefore the driver and passengers will continue to feel like they are in a tin can.

How to apply liquid fender liner

Many motorists mistakenly believe that liquid fender liner on the wheel arches of a car can only be applied by professionals from a special service. However, it is not.

Such an operation is quite feasible at home, but for this you will need enough time, tools and, most importantly, work skills (or at least good theoretical knowledge how this process is done). Many do not know which of the two options is better: contact a car repair shop or try to do everything on your own. It is important to know that if you are not sure that you have fully understood the principle of work, it is better to seek help from specialists. They are guaranteed to bring the wheel arches of your car in order. So, if you still decide to apply liquid fender liner with your own hands. You should act in accordance with the following algorithm:

• The fender liner should dry fairly quickly, so it's best to do it all in a heated garage. Naturally, there should be a minimum amount of dust in the air - otherwise it can seriously damage the coating.
• Raise the car to the required height. To do this, it is best to use a lift, which will give good and free access to the wheel arches. However, if there is none, a jack of sufficient height will do.

Raise the car with a jack

• Dismantle all 4 wheels and mudguards (of course, if they have not been dismantled by you in advance).
• Thoroughly wash and clean the wheel arches of the car. After that, they should dry completely in natural conditions. Use with this building hair dryer or other similar devices are not recommended.
• Close and carefully seal all brake mechanisms of the vehicle. This is done to avoid getting on them the remnants of the old coating or fragments of the new one.
• Thoroughly clean off all old anti-corrosion and paintwork. After that, remove the soil layer. The result should be pure bare metal. You will no longer need old coatings, as liquid wheel arch liners will replace them completely.
• Carefully and evenly apply liquid fender liner to all wheel arches. In this case, the layer must have a thickness of no more than 3 mm and be completely homogeneous and uniform.

"Liquid fender liners" are applied by spraying with compressed air and "pistol"

• After application, it is necessary to wait for it to dry completely (this may take up to several hours - it all depends on which materials you have chosen). After the coating has dried, it will be necessary to proceed with the application of bituminous mastic. To apply it, you will need a regular paint brush. It is better not to spare the mastic - it should lie in a dense thick uniform layer on all surfaces of the wheel arches.
• When the mastic dries, you will need to apply another layer of liquid fender liner. It is best to do this with a sprayer - this is more likely that the material will be able to penetrate into all the microcracks formed on the surface of the mastic after drying. Like the first layer, the second should be fairly uniform and uniform. The thickness, as in the first case, is 2-3 mm. Also, many experts recommend applying the final layer of liquid fender liner to the vehicle sills, including.
• After that, you should also wait for the material to dry completely, after which you can screw the wheels into place, etc.

Liquid fenders for wheel arches

As the experience of motorists who applied liquid wheel arch liners with their own hands at home shows, wheel arches acquire very reliable protection and last much longer. There is also a reduction in the noise level in the car while driving on non-paved roads.
