How to Repair Scratches on Plastic Bumpers?
2 Answers
Methods for repairing scratches on plastic bumpers: 1. Toothpaste: Toothpaste has a grinding function, equivalent to applying a layer of wax to the car, providing a good repair effect. However, toothpaste can only be used for minor scratches and is ineffective for deep ones; 2. Paint scratch repair agent: The repair agent has a grinding effect and can quickly repair the damaged part of the paint, but it also only works for minor scratches; 3. Touch-up paint pen: Using a touch-up paint pen can cover some small and shallow scratches, making them less noticeable. The effect is still somewhat different from the original factory paint, and the durability cannot compare to the original paint. The touch-up pen is only for local repairs, but the overall effect is relatively good.
A few days ago, I dealt with scratches on my car's bumper and felt it was worth sharing the experience. The key to repairing plastic scratches lies in assessing the depth and your willingness to DIY. For shallow scratches, start by thoroughly cleaning the surface with soapy water, let it dry, then gently sand the area a few times with fine-grit sandpaper dipped in water until the scratches fade. After that, apply plastic repair wax evenly and polish it—it’ll shine like new immediately. For deeper scratches, the process requires more care: after cleaning, apply a layer of specialized filler paste to level the surface, let it dry, then finely sand it with higher-grit sandpaper to ensure smoothness. Next, spray primer, original-color paint, and a clear coat for protection in sequence, applying each layer thinly with 10-minute drying intervals in between. The whole process demands patience, and tools like sandpaper and spray paint cans keep costs under 100 RMB, saving you a trip to the repair shop. But if you lack confidence, it’s safer to go to a professional shop—they have better equipment and precise color matching.
