How to Deal with Door Rust?

[DiMaddox]

Door rust can be handled in the following ways: 1. If the rust is on the surface and covers a small area, you can use water sandpaper to grind off the rust and then spray a layer of rust-proof paint; 2. If the rust has damaged the primer, the rust needs to be ground off, followed by primer spraying and then topcoat spraying; 3. If the door rust is severe, with large areas of paint peeling off, the rusted paint on the door must be completely scraped off, and then filled and leveled with putty. Car doors provide access for drivers and passengers and isolate external interference. To some extent, they can mitigate side impacts and protect the safety of occupants.
