The domestic auto industry readily absorbs all the technological delights of the global industry. This process is expressed both in fashion releases of sported versions of the best Togliatti models, and in the craze for new electronic assistants. But there are also many Russian traditions in this area, which are still quite relevant today. Body rust removers are just one of those. Another thing is that modern methods of dealing with metal damage are seriously different from Soviet "recipes". So, if until the 90s the metal was covered with tar and rubber-bitumen mastic, today anti-corrosion treatment of the body provides a wider range of effective methods.

The principle of action of anticorrosive

First you need to decide what exactly the car body should be protected from. Of course, first of all, this is contact with water, which can penetrate under the paintwork. But the rusting process most often begins at the points of contact of the metal with foreign materials, as well as with the electrolyte. Accordingly, any anti-corrosion treatment of the car body is aimed firstjust to seal the base. The effect of isolation is achieved in different ways, but the main task is to prevent contact of the surfaces of the structure with other materials. This does not mean at all that the entire body should be reinforced with anticorrosive. Most of the area is completely preserved under the factory layer of paintwork. Additional processing is required in the most vulnerable areas, including door pillars, spars with thresholds, wheel arches, etc.

Which cars fit?

In Russia, the popularity of anti-corrosion treatment is associated with the long-term nature of the operation of cars, while Europeans change cars every three years. If you plan to quickly change a used foreign car or a domestic novelty, then there is no point in such operations. Another thing is that anti-corrosion treatment of the body is necessary in cases of mechanical damage to its elements. Even the slightest chip requires appropriate protection. It is important to take into account another aspect - the presence of factory plastic protection, which is valid for 2-3 years. If road reagents and abrasives cannot start the reaction during this period, this indicates a high quality of the protective layer. But it’s also not worth placing special hopes on regular funds. When calculating for a long period of using the car, it still makes sense to turn to special services in a car service.

How is bodywork anti-corrosion treated?

Much depends on the specific material,which it is planned to cover the body, but in most cases the execution algorithm is the same. The first step is to prepare the surface. Specialists clean the car and dry it thoroughly. If there are traces of previous processing, they are removed. Next, a new agent is applied - again, processing techniques may be different. For example, paint is applied using sprayers, and mastics are applied with special spatulas. The main thing is that the anti-corrosion treatment of the body covers all problem areas. After that, the “working” zones are dried for several hours.

What materials are used in processing?

On the market you can find a huge selection of different protective equipment. The most common options include paints, mastics, films and primers. Film coating, in terms of sealing, is a good solution, but the slightest damage can lead to a sad result. Quite good reviews are received by bituminous mastics, wax mixtures and synthetic-based anti-corrosion materials. But here, each manufacturer has its own proprietary composition, the effectiveness of which is largely determined by additives in the form of bronze, zinc, rubber and polymer impurities. The advantages of combined agents include the fact that they can counteract both corrosion and other destructive processes. As a result, the overall service life of the car's load-bearing elements is also extended.

Anti-corrosion protection for the bottom

The bottom requires special protection as thisthe part is exposed not only to chemical properties, but also to mechanical damage. Accordingly, the film and paints and varnishes are completely rejected. It is possible to use mastics, but only from the category of strongly hardening. The most effective solution for protecting this part is considered to be a multi-layer coating, including a mixture of phosphates, supplemented with inclusions of aluminum or zinc. Anti-corrosion paint with protection from a primer or the same mastic is also introduced here. As a result, a kind of “pie” is realized that can protect the bottom from both corrosion processes and physical damage. The most radical way to protect this part of the car involves the installation of protective plates from the same combination of zinc and aluminum. But such designs are not cheap and in all variations require regular updates.

Question of price

Car services in most cases offer two approaches to performing processing. The first provides for the provision of full protection of the car, and the second - a partial adjustment of the state of problem areas. The funds used are approximately the same, and the cost depends on the class of the car. For example, a compact A-class can be partially improved for 5-7 thousand rubles. For SUVs, a complete anti-corrosion treatment is usually recommended, the price of which varies from 10 to 15 thousand rubles. Separately, the protection of hidden and hard-to-reach elements, which include the exhaust system, fender liner and sills, is evaluated. But in such cases, the most effective means are used - for example,thermal lacquer, anti-gravity films and liquid lockers. The cost of such protection is 3-5 thousand rubles.

Conclusion

A good help for the function of protective coatings will be the careful nature of the operation of the car. Keeping the body clean, timely restoration of the paint layer and gentle use of the car in bad weather are the main preventive measures available to any driver. Of course, corrosion protection also contributes to the prevention of destructive metal processes, but it may not be enough. In any case, the observance of preventive measures will allow to increase the intervals between updates of rust-preserving coatings. Also, do not forget that each body repair must be accompanied by a special treatment of the damaged area, whether it is the formation of a small chip, or the formation of a weld.
