They have developed special protective preparations that protect the body from acid and salt effects, as well as from chips caused by impacts of particles of rubble and sand. An example of such a development is the drug "Antigravel".
The drug "Antigravel" can be used both for new cars and for cars with solid mileage, helping to avoid damage to the body and mask them. And if we are talking about rare cars, then such a tool will help such "time capsules" stop corrosion and restore a decent appearance. There are much more open metal surfaces in machines that are not spoiled with plastics than in modern ones, and therefore there will be a lot of work for Antigravel.

Packaging
Many manufacturers of automotive chemicals, this drug is available in a liter bottle or in the form of an aerosol for independent use, or under a special gun. For the private trader, of course, the first option is more convenient, which does not require additional investments.
In addition, you can find "Antigravel" in several versions: black, gray, white and transparent. Thus, everyone will choose their favorite shade. Someone will want a contrasting color coating, and someone will try to make it almost invisible.

How does anticorrosive work?
Using the anti-gravity developed by the Russian company ASTROhim as an example, consider the principle of the composition.
ASTROhim Antigravel is developed on the basis of modified polyethylene - this provides the coating with high strength and elasticity, as well as decent shock-absorbing and wear-resistant qualities. Such a preparation successfully resists “meteor attacks” of small stones and sand. Moreover, the product contains corrosion inhibitors and protects the body from salt and acid exposure, which does not pass anyone on our roads.
This "Antigravel" is safe for paints and varnishes. They can cover the sills, the edges of the wheel arches, the bottom, body sections that are not protected from external influences by the wing flaps, the numerous levers of a complex independent suspension, the protruding ends of the threaded joints, etc. One of the important features that this drug has is that it does not drain when applied to a vertical surface: the anti-gravity film has excellent adhesion. At the same time, a durable polymer elastic coating does not become brittle with time, does not crack and does not crumble. It goes without saying that it is not afraid of exposure to heat and frost. We also note that transparent antigravel does not turn yellow neither from heating in the sun, nor from the effects of detergents and reagents.
Application technology
An aerosol bottle guarantees the user a soft, controlled spray of the drug. Drying proceeds quickly enough: after a couple of hours, painted products can be used. The complete formation of the polymer film occurs in 24 hours.
The manufacturer recommends a protective layer with a thickness of at least 100 microns - it is formed when applying the material in two layers with intermediate drying for 15–20 minutes. Estimated consumption of material is 280-380 g / m 2. In other words, one liter cylinder is enough to process the sills and wheel arches. If you want to protect the car on the bottom, according to the principle of “we see painted metal - we protect!”, We apply the drug in a couple of layers: approximately three packs of the product will be needed. The preparation should be applied in heat - the instruction recommends doing this at a temperature of +10 to +30 ° C. Naturally, the surfaces to be treated must be washed, dried, cleaned from peeling old coat and degreased before applying the preparation. In this case, "Antigravel" will reveal its abilities to the full.

Small bonus
Among other things, anticorrosive will bring a useful bonus to the buyer: Antigravel coating improves - surprise! - acoustic characteristics of the car. Modern man is a weak creature: from excessive noise, he has various health problems, from auditory to cardiovascular. But the thick (compared to the paintwork) film prevents metal surfaces from vibrating and somewhat dampens external sounds. As a result, the car becomes quieter.
