How to Repair Plastic Scratches on a Car?

First, remove the surface layer of polishing wax film, oil film, and other foreign substances. Use a wax-removing cleaner to clean the scratched area, then let it dry. Depending on the size and depth of the scratch, select appropriate sanding materials for sanding. Be careful not to sand through the paint layer.
Last time there was a small scratch on my car's dashboard, and I was quite worried at first. Later, I tried fixing it myself. For light scratches, using common household items like toothpaste or shoe polish, applying them on a soft cloth and gently rubbing in circular motions for a minute or two can blur the scratch—pretty hassle-free. For deeper scratches, professional tools are needed. I bought a plastic repair paste online, applied it, let it dry completely, then slowly sanded it down with sandpaper, and finally used a heat gun to restore its original appearance. Safety tip: don’t set the heat gun too high, and keep a distance to avoid melting the plastic. For prevention, avoid knocking objects against it, and regularly clean and wax plastic surfaces inside the car to extend their lifespan—saving money while having fun. If you really can’t handle it, I recommend going to a 4S shop for a mechanic; they have professional equipment for more reliable repairs, preventing small issues from becoming big problems.
