If the car paint is peeling, especially on a red car, which requires a more complex and meticulous repair process, it is recommended to take the car to a professional auto repair shop. The main steps are as follows:
1. Clean the damaged area: The area where the paint has fallen off must be cleaned thoroughly to ensure it is free of dust, dirt, etc.
2. Sanding: Use fine sandpaper to gently sand the edges of the paint-off area to make a smooth transition to the unpainted area.
3. Clean and dry: Wipe the sanded area with a clean cloth to ensure that there is no residual dust and completely dry.
4. Spray primer: Use a suitable primer and spray it lightly on the sanded area to cover it completely, then wait for the primer to dry.
5. Spray color paint: Use paint that matches the color of the car body and spray it lightly in multiple times. Wait for the paint layer to dry before spraying the next layer until the color is consistent.
6. Spray clear coat: After the color paint is completely dry, spray the clear coat protective layer, also spray it in multiple times and wait for it to dry completely.
7. Sanding and polishing: Finally, use very fine sandpaper to lightly sand the clear coat, and then polish it with a polishing agent to blend the repaired area with the surrounding car paint.
