Before applying anti -corrosion materials, it is necessary to conduct high -quality preparation of the body, which consists in its thorough washing. To do this, it is necessary to remove the rear and front bumper, all plastic elements, as well as shelters and all kinds of linings. Next, wash it out using autocomatics, and then dry the entire car, including the bottom and underground arches. Then, carefully inspect the car body. Finding places of corrosion, remove them by stripping with sandpaper to bare metal. Treat the cleaned areas with a passivating composition for binding and converting corroding elements of rust.
