If visible scratches are present without damaging the color paint, clean the surface first, then use a soft towel dipped in toothpaste to rub back and forth, followed by wiping with a clean towel; 3. If the color paint is damaged but the primer is intact, clean the surface thoroughly and apply wax for polishing, repeating the process several times; 4.
