Should You Remove Rust or Replace the Door for a New Car with Rusty Doors?

[OwenAnn]

For a new car with rusty doors, rust removal is quite convenient. Here are the specific details: 1. Light rust: If the rust is not severe, you can first use very fine water sandpaper dipped in water to gently sand away the rust spots. After completely cleaning it, apply a layer of primer to ensure the rust does not spread or worsen. For new scratches, you can clean them and directly apply primer. Generally, vehicles come with a small can of original paint; you can also buy a touch-up pen in advance. After the applied primer dries, sand it smooth with water sandpaper, then use the touch-up pen for coloring. Remember, applying primer has the effects of rust prevention and enhancing the adhesion of the topcoat. You can directly apply the touch-up pen. Small scratches or inconspicuous areas can be touched up using this method. 2. A handy tip: You can use toothpaste. Keep a tube of ordinary toothpaste in the car. When you notice small new scratches, apply a little. After rain or washing the car, it can simply act as a barrier, working fine in the short term. This is just a simple temporary solution. Ultimately, you will need to repaint for a thorough fix.
