How to Deal with Rust on Car Doors?

[DiTyler]

If rust is found on the car door, it should be treated promptly to prevent the rust from spreading. The treatment methods are as follows: Surface rust with small area: If the rust appears on the surface and covers a small area, you can use water sandpaper to grind off the rust and then spray a layer of anti-rust paint. Rust reaching the primer: If the rust has reached the primer, the rust needs to be ground off, followed by primer spraying, and then topcoat spraying. Severe rust with large areas of paint peeling: If the car door has severe rust with large areas of paint peeling, the rusted paint needs to be completely scraped off, filled and leveled with putty, and then painted after the putty hardens. Rust-through on the door: If the car door is rusted through, repair is generally not recommended as the effect is limited, and rust may reappear after some time. It is advisable to replace the door.
