Restoration of anti-corrosion and anti-noise coating of the bottom of the body and wheel arches

During the operation of the car, the coating on the bottom of the body is exposed to gravel, sand, salt, moisture. As a result, the mastic and soil are damaged and erased. Bare metal corrodes. In case of damage to the D-11A plastisol coating without disturbing the soil layer, clean the damaged areas from dirt and apply plastisol to a dry surface with an airless spray or brush. Dry the plastisol at 130°C for 30 minutes.

It is allowed to apply anti-noise mastic BPM-1 instead of plastisol, the drying of which can take place in natural conditions. Before restoring the coating, place the car on a lift, carefully inspect the bottom of the body and identify defects in the coating. Clean the bottom of the body from dirt, remove rust with a spatula, sandpaper or rust converter according to the instructions. Blow the bottom of the body with compressed air. Place the car on a lift in the mastic chamber and remove the wheels. Close the brake drums and discs with protective covers, isolate the driveline, mufflers, cables and other places that cannot be treated with mastic with thick paper and adhesive tape. With a rag soaked in white spirit, degrease the places cleaned to the metal.

Apply primer GF-073 to the cleaned places by spraying or brushing and hold for 5-10 minutes. Then apply by spray or by hand (brush or spatula) mastic BPM-1 on defective places with a layer of 1.0–1.5 mm. Overlapping on the old D-11A coating layer should be minimal. In the cold season, before use, keep the mastic in a warm room until the temperature rises below 20°C. In case of mastic thickening, dilute it with xylene, but not more than 3%. Clean the paintwork from contamination with mastic with a rag soaked in white spirit. Dry the mastic at 100–110°C for 30 minutes or at 18–28°C for at least 24 hours.
