A car, even one that has just rolled off the assembly line, is exposed to the negative effects of moisture - both atmospheric, and flowing along the road during rain, and forming in the form of condensation in the body cavities hidden from view. Of course, at the factory, cars are necessarily treated with special protective compounds, but their actions, as a rule, are not enough for a long time: reagents and high humidity cope with them very quickly. In our country, there are also complex climatic factors: the metal of the car is exposed to significant temperature changes, which accelerates the corrosion processes.

To reliably protect the car from rust, experts recommend treating the bottom, wheel arches and hidden cavities with anticorrosive immediately after purchase. There are a lot of anti-corrosion drugs on sale: based on bitumen, wax, corrosion inhibitors and other substances. Our review will help you choose the right product for any car: it contains only the most popular and well-proven formulations of well-known brands.

The best anticorrosive lines

10 DINITROL

Anticorrosive Dinitrol has proven itself in the domestic market: almost all buyers claim that this product, although not cheap, is very effective. In addition, the company offers an extremely functional solution for every part of the car: there are special tools for hidden cavities, underbody, muffler, engine compartment, as well as liquid wax. Having bought a new car, you can purchase a complete set for its anti-corrosion treatment.

The cost of Dinitrol aerosols, of course, is quite high, but with a compressor, the user can save almost 50% - liquid products in canned packaging are much cheaper. Another advantage is the presence in the company's assortment of means for protecting the engine, front body parts and even the floor in the cabin. In this case, all compounds can be applied independently, without going to the workshop.

9 SUPRA-SHIELD

Antikor Supra-Shield is made on the basis of corrosion inhibitors and water-displacing substances. The advantage of this composition is that it can be applied to a wet surface without waiting for final drying, as well as at any air temperature. Another plus - full processing of the car is allowed, including paintwork. Due to its liquid texture, Supra-Shield penetrates even into formation rust, reliably stopping the corrosion process.

Consumers are satisfied with the fast application process, as well as the long warranty period - 3 years in the case of a one-time treatment, as well as the more than reasonable price. According to reviews, this anticorrosive is the best choice for protecting welded seams due to its high fluidity. However, there are also disadvantages: strong odor and long runoff of the product from the hidden cavities of the car.

8 PRIM

In the line of anti-corrosion compounds Prim, which is produced by the Russian company Primula, there is almost the entire range of protective components: bituminous anticorrosive for the bottom, wax composition with corrosion inhibitors for hollow cavities, as well as special "liquid fenders". The latter is especially popular for crossover wheel arch protection. It should be noted that the corporation produces, among other things, conveyor protective chemistry, which is used at VAZ factories.

The best product in the Prim series, according to customer reviews, is Prim-W anti-noise. The manufacturer claims that when this composition is applied to a new car, corrosion, damage from impacts of small stones and noise in the cabin can be forgotten for at least 12 years. The disadvantages of such an anticorrosive agent are a long drying time (about a day).

7 NEW

The domestic company Novax has been working in the anti-corrosion market for over 15 years. During this time, the company's technologists have developed several successful series of mastics and sprays to protect cars from rust.Means for application on the bottom have proven themselves well among motorists. A particularly successful version of such an anticorrosive agent is Nova BiZinc, which can be used if rust has already appeared. The product contains a stabilizer, a reinforcing filler and a corrosion inhibitor.

Buyers are especially pleased with the fact that this anticorrosive can be applied already at 5 degrees. According to reviews, it keeps from being excellent and really stops the corrosion process that has already begun. The disadvantage is that when it gets on the front parts of the body with paintwork, this mastic is very poorly scrubbed, which is the reverse side of the excellent adhesion properties of the anticorrosive.

6 Cordon

The Polikom-Plast company offers a whole line of anti-corrosion agents under the Cordon brand: both in the form of mastics for application with a brush, and in the form of aerosols. This protective coating is a polymer composition based on bitumen and synthetic resin. After application and drying, it forms a black, waterproof and heat-resistant film on the surface, which prevents corrosion from developing.

Buyers note the excellent adhesion of the product, as well as the fact that it is almost not washed off both with plain water and when washing with auto chemicals. In addition, for a car treated with such a composition, the sound insulation of the body is improved. There are also disadvantages: you need to work very carefully so as not to stain the painted parts of the body or glass. At the same time, it is highly desirable that during the application of the coating the ambient temperature is above zero - at low temperatures the composition quickly solidifies.

5 HB BODY

A very popular line of anti-corrosion agents in our country, HB BODY is distinguished by good quality at a reasonable price. The Greek company produces protective products, focused mainly on professional workshops, but the range also includes sprays for self-application. The most popular anticorrosive company is HB BODY 930 on a bitumen-rubber base, which, among other things, also has soundproofing properties. Thanks to the well-chosen composition, after application, the product remains elastic and protects the underbody and wheel arches from the impact of gravel and small stones.

Buyers are satisfied with the value for money of this anticorrosive. Such protection lasts for a long time, you just need to be very careful about the preliminary preparation of surfaces and carefully follow all the manufacturer's recommendations. The only drawback is an unpleasant odor that disappears after the completion of polymerization.

4 RUST STOP

This anti-corrosion agent comes from Canada, where special attention is paid to the environment. Therefore, RUST STOP is completely non-toxic and does not have an unpleasant odor, which is often the case for products of other manufacturers. It is produced in the form of a gel-like composition for the underside of a car (there are options for application with a brush and for spraying) and in the form of a semi-liquid spray for cavities). The chemical-physical properties of the composition are selected in such a way that it penetrates into microcracks, displaces moisture and stops the oxidation process of metal surfaces.

Customers praise the easy self-application of the product, as well as its resistance to moisture and reagents. Among the minuses, it is mentioned that due to the liquid texture, this anticorrosive can flow out of the cracks for several months after the initial treatment. Although the manufacturer declares the possibility of applying RUST STOP immediately to rust, experienced car owners advise nevertheless to make a thorough preliminary preparation of the body.

3 TECTYL

Valvoline, the manufacturer of this anti-corrosion agent, produces a whole line of protective products for all cases: paraffin-based cavity sprays and denser bitumen compositions for underbody, tanks and other auto parts exposed to intense water and reagents. Customers especially appreciate Tectyl body safe with zinc, which is well suited for harsh environments.

Tectyl sprays in cans are significantly more expensive than canned products of the same formulation, but the user friendliness is definitely worth it. To process cars with canned Tectyl, you will definitely need a compressor - it is not recommended to apply them with a brush. The disadvantages of this anticorrosive are the high price and the need for thorough drying of the car before processing. But the durability of the coating, according to experienced professionals, is one of the best on the market.

2 MERCASOL

The entire line of MERCASOL anticorrosives is produced only at the factories of the Auson corporation in Sweden, so the quality of the compositions is consistently excellent. The manufacturer guarantees that the coating retains its protective properties for 8 years after application, if the work is carried out in compliance with the technology. The most popular anticorrosive in the series is MERCASOL 3, based on bitumen with wax, which is used to protect the underbody and wheel arches from rust.

Another feature of the series is Noxudol preparations, which do not contain solvents and therefore are particularly environmentally friendly. This option is perfect for those who have allergies or small children in the family. There are specialized formulations for underbody, arches and cavities. According to the reviews of experienced car owners, MERCASOL bitumen anticorrosive preparations are the record holders in terms of durability among competitors. There is only one drawback of this series of anti-corrosion agents - the high price.

1 Krown

This oil-based anti-corrosion compound has two main advantages: firstly, it does not spoil the paint layer of the car (therefore, there is no need to partially disassemble it) and, secondly, it has water-displacing properties, so that the car can be processed immediately after washing, without waiting for complete drying. The latest development of the Canadian company - Krown 40 can be applied directly to rust and is used to treat all problem parts of a car - underbody, wheel arches, hidden cavities.

Consumers especially like the fact that a complete car wash using Krown technology takes no more than two hours, including washing. Experienced motorists are of the opinion that it is still better to use more viscous compounds to protect the bottom. The company's specialists advise to repeat the application of the anticorrosive agent once a year, especially for those cars that are operated in severe weather conditions. Car owners praise the practical packaging of the product in aerosol cans, which is especially convenient for self-cleaning of hidden cavities.
