Will a Car Door Rust If the Paint Chips Off?

[VanAiden]

Car door will rust if the paint chips off. Reasons for rusting after paint chips off: If car paint chips are left unattended for a long time, they will rust. During daily driving, minor scratches are inevitable. Rust mainly occurs when the exposed metal body comes into direct contact with the external environment after collisions or scrapes. Methods to prevent rusting from paint chips: If the car paint is damaged and you don't want or can't repair it immediately, you can apply nail polish to prevent the exposed primer from rusting. Using correction fluid is not recommended as it can soften when wet. A touch-up paint pen will suffice. Since fenders are made of metal and the primer is already exposed, rust will occur. It's recommended to first smooth the edges with fine sandpaper, then repair with a touch-up paint pen, and finally apply a layer of wax.
