How to Repair Car Paint Scratches by Yourself?
3 Answers
For hairline scratches, methods like polishing or applying abrasive compounds are usually sufficient for removal. Simply gently wiping can make the hairline scratches disappear. For shallow scratches, just prepare a tube of toothpaste. Toothpaste is highly effective for superficial scratches that haven't damaged the car's primer. Medium to deep scratches cannot be repaired by abrasion. They require filling with putty to level the surface, followed by touch-up painting. For more severe deformations, sheet metal repair is necessary.
Last time my car got a scratch in the parking lot, and I found it quite satisfying to fix it myself. First, wash the car clean and dry it, then find a shady spot to work—avoid direct sunlight. Gently run your fingernail over the scratch; if it feels shallow, you can buy some polishing wax or even use toothpaste as a temporary fix—apply it and buff in circular motions to cover it up. If the scratch reaches the base coat and you notice a color difference, get a touch-up pen that matches your car's color. Test the color on a small area before applying it fully. When applying the touch-up paint, do it in thin layers—apply one layer, wait a few minutes for it to dry, then apply another. Avoid applying it too thick at once, as it may overflow and look messy. Once fully dry, use 2000-grit sandpaper with water to lightly smooth the surface. Finally, spray some clear coat for protection and polish it to a shine. This method saves money and hassle. While it might not be perfect, it's great for practicing your skills. There are plenty of tutorial videos online to help beginners get started.
As a long-time car owner, I often deal with minor scratches. The key lies in preparation: ensure it's sunny with moderate temperatures, around 20 degrees Celsius being ideal for operation. Wear gloves to prevent hand injuries, thoroughly clean the scratched area first, and dry it with a blower. After assessing the depth, purchase touch-up paint matching your car's color code. Apply thin layers as instructed, waiting for each layer to dry completely before adding the next to minimize bubble risks. Then lightly sand until smooth, and finally apply clear coat for protection. Remember to ensure proper ventilation and safety, testing the paint in an inconspicuous spot beforehand to check for adverse reactions. These small repairs save considerable repair costs, but for deep scratches or major damage, it's best to avoid DIY and seek professional help directly.
