How to deal with a white scratch on a black car?
2 Answers
Black car scratches showing white can be handled with these methods: 1. For minor scratches where the damage is on the surface layer of the paint, it can be completely repaired by waxing. 2. For slightly larger scratches that haven't penetrated the primer, a touch-up pen can be used. 3. Use toothpaste for repair. Additional information: 1. Automotive painting refers to applying a layer of paint to the car's surface to protect it. Automotive painting generally uses baked paint. 2. In automobile manufacturing plants, after the frame and body are welded, the next process is painting. Types include regular paint, metallic paint, and pearl paint.
Oh dear, my black car has also encountered similar scratches revealing the white base—it feels quite distressing! I've dealt with it myself a few times, so here's my experience: First, clean the scratched area thoroughly by wiping off dust and dirt with a soft cloth dampened with water to avoid making it worse during treatment. Then, assess the depth of the scratch. If it's just a superficial light scratch, you can try using toothpaste or scratch repair paste—apply a small amount and gently rub in circular motions with a clean cloth. This low-cost method may have limited effect on exposed white areas and is only suitable for ultra-light scratches. If the white base is exposed, it likely means the primer is damaged, and you can't take it lightly. I recommend buying a touch-up paint pen matching your car's black color (available online for just a few dozen yuan). Shake it well before applying, then dab it on evenly in small amounts—don’t overdo it. Let it dry for a few hours after application. Finally, lightly polish the area with a polishing compound to smooth it out. Remember to work in a shaded spot to avoid high temperatures affecting the results. For deep or large scratches, DIY fixes may not look good and could lead to rust—in such cases, it’s safer to visit a professional repair shop for color-matched spray painting to prevent future rusting. When washing your car, avoid using stiff brushes or high-pressure water jets directly on the body to minimize such scratches.
