Scratches on the body can be caused by many factors. Even the most perfect paint can be scratched by car accidents, vandalism, poor parking techniques, or other parking accidents. These scratches affect the aesthetics, but it is quite expensive to go to the workshop to re-paint or re-paint. You can try erasing superficial scratches with toothpaste, removing small scratches with scratch repair products, or fixing deep scratches by sandpaper sanding and repainting.
1 Touch the scratches with your fingernails to see if they are shallow or deep. If the nails are not stuck in the scratches, they are superficial scratches, and perhaps toothpaste can deal with them. If the nail is stuck in the scratch, it means that the scratch is deeper and you need to use a professional scratch repair product.
2 Wash and dry the scratched area. Before applying toothpaste, make sure the scratched area is very clean, otherwise rubbing dirt and debris into the scratch will only make the scratch worse. You can take your car to the car wash center or do it yourself. If you choose to wash your car yourself, wet the car with a hose to remove most of the dirt and debris. Then use a large sponge or car wash brush to apply the car-specific soap to the car. Make sure all surfaces are covered with soap and rinse off with a hose. Finally dry the car with a clean dry towel.
3 Squeeze the coin-sized toothpaste onto a wet microfiber towel. The microfiber towel must be wet enough, but not dripping. Squeeze the coin-sized toothpaste onto the towel and adjust the specific amount according to the scratch area. Whitening toothpaste works best, but you can try any toothpaste you have on hand. You need to apply toothpaste to the car with a soft and clean microfiber towel to avoid further damage to the car by the friction of the towel.
4 Rub the toothpaste into the scratch area in a circular motion. Press down on the microfiber towel to rub the scratch in a small circle. Keep making circular motions until the toothpaste is evenly distributed on the surface. Push a little harder, but not too hard.
5 Wash off the toothpaste. After wiping off the scratches, rinse the scratched area thoroughly to remove the remaining toothpaste. Spray the car with a hose and dry it with a microfiber towel. You can also wipe off the remaining toothpaste with a wet microfiber towel.
6 Repeat up to 2 more times. The toothpaste method needs to be used more than 1 time to remove the scratches. Check the area to see if the scratch is still clearly visible, repeating 1-2 more times if necessary. Do not use this method more than 3 times so as not to damage the clear coat on the paint surface.
1 Wash the car and make sure there is no dirt or debris inside the scratches. Before using any product or wiping, be sure to clean the scratched area first. Any dirt and debris that remains on the surface will leave more scratches when wiped later. Wet the car with a hose and apply soap to the body with a sponge or car wash brush. Rinse the soap and dry the car with a microfiber towel. Be sure to wash your car with car-specific soap.
2 Purchase scratch repair products or sets. You can buy scratch repair products in the auto supplies department of a car supply store or a large one-stop shop. These products are usually sold in sets that contain scratch repair products and polishing pads needed to apply the product. If you're not sure which product to buy, ask the clerk. Employees who work in auto supply stores are often familiar with these types of products. Microfiber towels are gentle on car surfaces and are suitable for applying scratch repair products. Some products even come with mechanical polishing tools that you can use to remove scratches.
3 Scratch repair pen is best used to repair minor scratches on body clear coat. However, if the scratches have gone deep or through the paint, you may need to take the car to the workshop. Pour coin-sized scratch repair product onto the polishing pad. Adjust the dosage according to the scratch area. Squeeze the product onto a polishing pad or microfiber towel and fold it in half so that the product is evenly distributed on the surface of the polishing pad or rag. Before you start wiping, make sure the product is evenly distributed over a rag or polishing pad.
4 Rub the product into the scratches and surrounding areas. You can circle or wipe back and forth to choose the method that is most comfortable for you and covers the scratches completely, but don't change directions halfway after choosing a direction. Wipe back and forth or in circles only. Wipe for a few minutes to spread the product evenly over the scratches. Use light to moderate force to rub the product onto scratches.
5 Wipe off residual product. After wiping, wipe off the remaining product with a clean microfiber cloth. Polishing in a circular motion has just wiped the surface of the product. Do not allow the product to dry out on the surface of the car. Check the manufacturer's instructions to learn how to remove residual products.
6 Repeat 2-3 times if necessary. See if the scratches are still clearly visible. If yes, you can repeat steps above 2-3 times. Do not repeat too many times so as not to damage the clear coat on the car paint. Before repeating the steps above, be sure to check the manufacturer's instructions.
2 Sanding scratches, scrape off the top layer of paint. Fix the 2000 mesh wet and dry sandpaper to the sandpaper pad, hold the grip on the sandpaper pad, and start sanding the scratches. Grind for 10-15 seconds at a time, then stop and check to see if you need to grind deeper. Sand in the direction of the scratch. Do not reverse sand to avoid creating more scratches. If necessary, rinse with water so that the surface can be checked more clearly to see if it has been sanded to the bottom of the scratch. If the scratches are darker than the clear coat, use a rough 1500 mesh sandpaper to sand the surface, and then use 2000 mesh sandpaper to remove the scratches caused by the previous sandpaper. Make sure there is no dirt or debris between the sandpaper and the surface of the car so as not to create more scratches.
3 Rinse and dry the scratched area. Wash away the debris that occurs when grinding scratches. Then dry the surface with a clean microfiber towel. Do not use dirty or old rags as this may leave more scratches on the surface of the car.
4 Spray several layers of primer on the polished area. Buy an aerosol primer that can be sanded with sandpaper. Spray the primer onto the freshly sanded area. Spray back and forth, then wait 5-10 minutes, the first layer of primer dries before spraying the second layer, a total of three layers. Try to choose a primer that is similar in color to the original car paint. You won't find a primer of the same color, but you can find the same topcoat.
5 spray several layers of the same topcoat as the original car paint. Next, you need to spray the primer with the same color as the rest of the car. Wait 5-10 minutes after each spray for the topcoat to dry completely. To ensure you find the same topcoat, you can ask the car manufacturer about the hue of the topcoat. You may then be able to buy the topcoat at the auto accessories store or order it specifically from the car manufacturer.
6 Seal the freshly patched paint by waxing. Apply high-quality carnauba wax to the surface of your car and polish it with a polishing pad or microfiber cloth. You can purchase a car wax set that contains all the supplies you need to wax your car, including car wax, polishing pads or microfiber cloth. Squeeze the coin-sized car wax onto a polishing pad or cloth and start waxing, adding more if necessary. Press the polishing pad with medium force and wax in a circular motion. Continue wiping until the wax is evenly distributed and the surface of the car looks shiny.
