How to Repair Scratches on Car Plastic Shells?
2 Answers
Methods for dealing with scratches on car plastic shells are as follows: 1. Minor scratches: Use a compound to treat them, wiping in straight lines, then apply wax—first coarse wax, followed by fine wax, moving in the same direction from the inside out. This will remove almost all fine scratches. 2. Scratches without exposed primer: Shake the touch-up paint pen well before use, then apply the primer like nail polish. 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 dries, apply fine wax. 3. Scratches with exposed primer: First, wash and dry the car, then apply rust remover to the scratched area. After 10~15 minutes, wipe off the rust remover with a tissue to prevent further rusting. 4. Dent repair: The tool required for dent repair is a pry bar. It is mainly used to push the dented steel outward from the inside. The technique must be delicate, with slight adjustments being key. Then, use a rubber hammer to tap from the outside inward to restore the overall shape. Finally, use a sharp object like a pencil tip to fine-tune any protruding marks on the car body.
Don't panic if your car's plastic shell gets scratched—I've been there too. For light scratches, thoroughly clean the affected area with soapy water, then gently sand it with fine sandpaper until smooth. Apply car-specific polishing compound and buff with a cloth for a few minutes to restore shine. For deeper scratches, try using a heat gun: evenly warm the plastic from a distance to soften it, then reshape while it's hot—but be careful not to overheat and burn the plastic. Afterwards, spray a layer of clear protective paint to set the color. The whole process takes about half an hour with decent results, but beginners should practice on inconspicuous areas first. I recommend buying a high-quality car wax and applying it regularly to effectively prevent new scratches and keep the plastic surface durable.
