If the rust is not very severe, you can first use very fine sandpaper dipped in water to gently remove the rust spots, wipe it completely clean, and then apply a layer of primer. You can also buy a touch-up paint pen in advance. After the applied primer has dried, use sandpaper to smooth it out, and then use the touch-up paint pen for color treatment. Keep a of ordinary toothpaste in the car. If you notice small new scratches, just apply a little bit of toothpaste on them.
