How to Deal with Rusty Car Doors?

[Alex]

Methods to handle rusty car doors: 1. If the rust is on the surface and the area is small, you can use water sandpaper to grind off the rust and then spray a layer of anti-rust paint; 2. If the rust has damaged the primer, you need to remove the rust by grinding, spray the primer, and then proceed with topcoat spraying; 3. If the car door is severely rusted with large areas of paint peeling, it is necessary to completely remove the rusted paint, fill and level it with putty, and then spray paint after the putty hardens. Causes of car door rust: After collisions or scratches, the metal body is directly exposed to the outside. Besides common collisions, scratches, and rust from long-term parking, another situation is when small stones kicked up by the tires of the car in front cause small impacts during driving, leading to tiny paint peel-offs and small rust spots. Regularly inspect the car body, engine cover, and around the car, and address any issues immediately once discovered.
