Does a deep scratch on the car door require a full repaint?

A scratch on the car door does not necessarily require a full repaint. Minor scratches on a car can often be remedied through polishing and waxing. However, if the scratch is deep and large, it is advisable to visit a professional repair shop for proper treatment. Steps for polishing: 1. Wash the entire vehicle. Use a high-strength paint cleaner to wash the car thoroughly, ensuring no dust particles remain that could cause further scratches during the polishing process. 2. Sand with water sandpaper. 3. Perform coarse and fine grinding. Use a polishing machine with coarse polishing compound to grind out the sandpaper marks. Then, apply fine polishing compound for detailed grinding. 4. Polish. Use a mechanical polisher with a mirror-finish treatment agent to remove swirl marks left by the coarse polishing compound, achieving a mirror-like finish on the paint. Method for applying liquid wax: 1. Clean the car thoroughly before waxing. A dirty car should not be waxed, as dust particles have tiny edges that can scratch the paint when rubbed back and forth during the waxing process.
