Car body, even new, needs constant protection. During the operation of any vehicle, mechanical damage, chips, scratches are not excluded. At the site of the defects formed, chemical reactions begin to intensively under the influence of a powerful oxidizing agent — oxygen. As a result of the flow of anode and cathode processes, the iron from which the car body is made is restored, forming a loose coating called corrosion. Car body protection is to stop the course of these chemical reactions and prevent the formation of new processes.
