To remove scratches from black plastic bumpers, follow these steps:
- Clean the Area: Wash the scratched area thoroughly with soap and water, then dry with a microfiber cloth to remove any dirt and debris.
- Sand the Scratch: Start sanding the scratches with coarse sandpaper (200 grit) gently in circular motions to level the surface, then progress to finer grits (800 and 2000) to smooth the area further.
- Apply Heat (Optional): For deeper scratches, carefully apply heat with a heat gun to make the plastic expand, which can help reduce scratch visibility—be cautious to avoid warping.
- Polish: Use a good-quality car polish to restore the shine with a microfiber cloth.
- Protect: Finish with a coat of car wax to add shine and protect the bumper from future damage.
Additional tips include gently using a Mr. Clean Magic Eraser to smooth scratch edges before dressing the plastic and using "Back to Black" or similar trim dressing to even out color differences and make scratches less visible. Deep gouges may need plastic putty filler or professional repair. Avoid aggressive sanding which can remove texture and cause uneven appearance. This approach works well for minor to medium surface scratches on black plastic bumpers, restoring appearance without repainting or full replacement.
