What to Do When a White Car's Paint Gets Scratched?

Solutions for scratches on a white car's paint: 1. Polishing: Polishing is only suitable for minor scratches. Moderate friction helps eliminate fine scratches, but excessive polishing can thin the paint and eventually wear it through. 2. Touch-up painting: For deeper scratches, if the area is small and you have good DIY skills, you can do the touch-up yourself. For larger scratches, it's recommended to visit a 4S shop for professional repair. Steps for touch-up painting: 1. Clean the scratch before repair, using 800-grit sandpaper and a sanding block to smooth the scratch. 2. If the scratch is deep, use filler to level it. 3. After the filler dries, use 800-grit sandpaper and a sanding block to smooth the scratch again, then wipe it clean with a towel. 4. Gently sand the surrounding area with 2000-grit sandpaper until it becomes matte, then clean it. 5. Use a cleaning pad to wipe around the scratch before applying touch-up paint, then spray with clear gloss varnish.
I just had this happen last week - my white car got scratched in the parking lot. Don't panic first, check if the black primer is exposed. If it's just the surface layer, like in my case, buying a white touch-up pen can solve it. Clean the scratch thoroughly, apply the paint slowly along the scratch line, then polish after it dries. If the primer is damaged or the area is large, you'll need to go to a repair shop. My neighbor tried DIY spray painting and ended up with uneven color, costing him more in the end. Remember white car paint tends to yellow, so regular waxing after repair is especially important, otherwise the color difference will become obvious in a couple years. After repair, avoid washing the car immediately in rainy weather - new paint needs about a week to fully cure.
As a long-time car owner, I've dealt with several paint scratches. White car paint is thin, so for minor scratches, try using toothpaste and a soft cloth to polish—it's cost-effective and convenient. If the metal is exposed, apply a rust-proof pen first to prevent rust, which can cause bigger issues later. Touch-up paint kits are available online for just a few dozen yuan, including sandpaper and hardener, but make sure to pick the right color. I once checked the paint code using my VIN and bought pearl white, but it still had a slight mismatch. Later, a technician explained that touch-ups require treating the entire panel for uniformity, especially on large surfaces like doors. I recommend going to a professional shop—they have paint-mixing rooms for precise color matching, and the car is usually ready in half a day, costing around 200-300 yuan.
