Anti-corrosion treatment of the frame and bottom of the car.

Anti-corrosion treatment of the frame and bottom of the car. You can see the photo here. vk.com/id574604230 For used cars, you need to be careful. Anti-corrosion treatment must be renewed every 2-3 years. In large cities, the process of destruction of the anti-corrosion protective coating is faster. This is due to the high concentration of harmful factors. After buying a used car, it is recommended to make it anti-corrosion treatment. The frequency and nature of the treatment depend on the operating conditions, the materials used, the volume of the previous anti-corrosion layer and the observance of technologies during operation. Preparation: Using a lift or jack, dismantle the wheels. Remove fenders, mudguards and protective covers. The body is washed with a powerful jet. Apply detergent. After waiting for the chemical solution to work, wash off its remnants with clean water. Covers and fenders are cleaned separately. Dry the bodywork. For this purpose, a heat gun is used. Before this procedure, you need to make sure that the plugs are removed from the drainage holes. As soon as the body is completely dry, it is carefully inspected. Determine the condition of the protective coating and the general condition of the body. They look for rust, deformation, damage, peeling of the protective and decorative coating, etc. They cover parts that cannot be processed. These include brake pads, engine, exhaust pipe, some parts of the suspension. Oxygen sensors, radiator system, various electrical connectors. After completing the preparatory work step by step before starting the anti-corrosion treatment of the frame and the bottom of the car. Rust is sanded, a rust converter is applied to clean rust-affected metal surfaces. The converter produces the reduction of iron oxides to a metallic state. The corrosion inhibitor in the preparation improves the corrosion resistance of the treated surface to oxidative processes. Then the rust converter is neutralized with a soda solution in order to stop the further process. The next stage of work is the degreasing of the treated surfaces. Before applying acid and acrylic primer and painting. An anti-corrosion coating is applied to the dried bottom. Waiting for it to dry. Mastic is applied to the surface in several layers. After applying the next layer, a five-hour break is made. As a result, a protective coating with a thickness of approximately 2 mm is formed. Wheel arches are processed in exactly the same way as the bottom of the car. The surface of the arches is exposed to gravel, pebbles and sand flying out from under the wheels. Hidden cavities of the car, arches, thresholds, side members, frame are also processed. At the end of the work: Install the plugs in their places. If additional holes were created during the work, they are closed with rubber plugs. Check how tight the rubber seals are. Remove the rest of masking materials. Remove the ants that have fallen on the body
