How to Repair Scratches on Car Interior Plastic Trim Panels?
2 Answers
For cases where the scratches on the car interior plastic are quite severe, car owners should not attempt repairs casually. It is best to seek professional auto detailing shops to treat the plastic surface. You can clean the scratched hard plastic area thoroughly, then use professional materials to spray paint it. Minor scratches can be repaired through simple spraying.
When there are scratches on car interior plastic trim panels, you can first try DIY repair methods. For example, prepare a fine sandpaper to gently sand the scratched area to remove burrs, but be careful not to over-sand and damage the plastic. Then use a heat gun on low setting to heat for a few seconds to soften and fuse the plastic, which yields good repair results. Remember to wear gloves to protect your hands. If the scratches are shallow, purchase a plastic repair paste to apply and let it sit for about a day—it can fill the gaps and restore surface smoothness. The key is to clean thoroughly to prevent dust from affecting the repair. When parking, avoid direct sunlight to prevent plastic aging. These methods are cost-effective and practical, but improper operation may worsen the damage, so beginners should start with simple sanding.
