For minor car scratches, body wax or toothpaste can be used for repair; for slightly larger scratched areas, a touch-up paint pen can be used as an emergency solution, followed by professional treatment at a 4S shop. Methods to repair car scratches: Minor scratches can be completely repaired by waxing. After straight-line wiping with a compound, apply wax—first coarse wax, then fine wax, moving in the same direction from the inside out—to remove fine scratches. Alternatively, apply body wax to the small scratches, soak a towel in warm water, and repeatedly wipe the waxed area several times to effectively eliminate minor scratches. For some fine scratches, you can also prepare a piece of water sandpaper and a basin of water. Soak the sandpaper in water, take it out once wet, and gently sand down the fine scratches. For thin but deep scratches, putty can be used for repair. Sand the scratched area with sandpaper, clean the damaged spot thoroughly, carefully apply putty to ensure it fully fills the gaps, then apply the compound and wax. For slightly larger scratches, a touch-up paint pen can be used as a remedy. Before use, shake the paint inside the pen well. You can add a certain amount of thinner to the touch-up pen to ensure smooth spraying. Carefully spray the area that needs repair, and once the touch-up paint has dried, apply fine wax. Alternatively, use water sandpaper for sanding.
