How to Repair Car Door Scratches?
2 Answers
Methods for repairing car door scratches include: 1. For hairline scratches, simply use polishing or apply a rubbing compound to remove them; 2. For shallow scratches, applying toothpaste to the scratch is sufficient, as toothpaste is highly effective for minor scratches that haven't damaged the car's primer; 3. For small dents with a depth not exceeding 5mm, fill with putty to level the surface, then proceed with touch-up painting. If the scratch exposes bare metal, first clean the surface of any rust or welding residue, sand it smooth, apply a rust-preventing neutralizer, spray a primer, and repeat the painting, drying, and sanding process to complete the repair.
Speaking of car door scratches, I just dealt with a shallow one myself last week. If the scratch hasn't reached the primer and only the surface paint is affected, you can use toothpaste or scratch repair wax. Apply some toothpaste to a soft cloth and gently polish the scratched area in small circular motions. After rinsing with water, most fine scratches will fade. If the primer is exposed, don't panic—you can buy a touch-up kit online for just a few dozen yuan: first, use sandpaper with water to gently smooth out any rough edges, then apply filler of the same color to level the depression. Once dry, sand it with fine sandpaper and finally spray paint. Keep the spray can about 20 cm away and spray evenly in three thin coats for the most natural finish. However, if metal parts expose the primer, rust prevention should be a priority, while plastic bumpers aren't as urgent.
