How to Deal with Scratches Caused by Opening Car Doors?
1 Answers
For scratches caused by opening car doors, you can apply toothpaste to minor scratches and gently rub to remove them. Toothpaste contains fine particles that gradually polish away visible scratches when rubbed. For such minor damage, besides passively accepting it, you can also take proactive measures to prevent it. Applying wax once every 1 to 2 months or placing anti-wear patches in areas prone to scratches can help avoid minor scratches to some extent. Hairline Scratches: Hairline scratches can be removed by polishing or applying a rubbing compound. Usually, a gentle rub is enough to make the hairline scratches disappear. Moderate to Deep Scratches: Moderate and deep scratches cannot be repaired by polishing. For small dents not exceeding 5mm, you can fill them with putty to level the surface and then proceed with repainting. If the metal is exposed at the scratch site, first clean the surface coating, rust, and welding slag, sand it smooth, apply an anti-rust oxidant neutralizer, spray primer, and repeat the painting, drying, and sanding process to repair. Deep Scratches: For severe deformations, sheet metal work is required. Handling deep scratches demands higher technical skills. For deep but narrow scratches, colored putty can be used for repair. Use sandpaper on the scratched area, being careful not to expand the damaged surface unnecessarily. The key is to clean the dirt thoroughly. Apply the putty carefully to ensure it fully penetrates the scratch. Finally, apply a compound and wax to finish the job.
