How to Deal with Scratches on a White Car?

Treatment methods are as follows: 1. First, carefully wipe the scratch and the surrounding paint with a chamois cloth, then apply everyday toothpaste to the scratched area. Ensure the application is even, and reapply after rain or car washing. Note that applying toothpaste to the scratch only provides temporary protection and prevents rusting. 2. Start by sanding with very fine-grit sandpaper, sanding in straight lines to remove rust spots and toothpaste, then apply a thin, even layer of primer. After the primer dries, sand it smooth. 3. Carefully apply two layers of masking tape along both sides of the scratch, exposing only the scratch. It's best to apply multiple layers of tape. Be meticulous when applying to fully enclose the scratch, ensuring optimal touch-up results. 4. If the car came with a small can of original paint, apply it evenly over the primer with care. 5. If original paint is unavailable, use a touch-up pen. Shake the pen thoroughly before use and apply multiple coats, waiting 5-10 minutes between each. Once completely dry, sand smooth with sandpaper.
I enjoy DIY car repairs to save money and gain a sense of achievement. For white car scratches, the treatment depends on their depth. If it's just a light scratch without exposing the primer, first clean the stain with water, let it dry, then apply toothpaste or a dedicated car scratch repair paste on a soft cloth and gently rub for a few minutes—this usually helps fade the scratch significantly. For deep scratches where the metal base is visible or there's obvious color loss, it's a bit more complicated. You'll need to carefully fill them with a white touch-up paint pen—avoid applying too thickly to prevent bumps. After drying, lightly sand it smooth with 2000-grit sandpaper, then apply a layer of car wax to protect the paint. Remember to match the paint color code; check your car model's color chart online. Last time I fixed a scratched rearview mirror myself for less than 50 yuan, which felt much more convenient than going to a shop. However, beginners should avoid working on large areas at once to prevent uneven color. To prevent scratches, park farther away from others and avoid using hard brushes when washing the car.
