What are the methods to deal with car scratches?

After treating with a compound, apply wax in the same direction from the inside out. The functions of car wax include the following three points: 1. Waterproofing effect: Water droplets remaining on the car body surface can, under the effect of focusing, reach temperatures of 800-1000°C at the focal point, greatly affecting the paint quality and lifespan. Water droplets can also cause rust on exposed metal surfaces. 2. High-temperature resistance: It effectively reflects incident light from different directions, preventing the paint or base color from aging and discoloring due to incident light. 3. Anti-static effect: The principle is to block the friction between dust and the car's metal surface. Due to differences in the thickness of the wax layer and the wax's own adhesion ability, the anti-static effect varies to some extent.
I find that scratches on cars are quite common, especially when parking or accidentally brushing against objects during daily driving. For minor scratches, like surface abrasions that haven't reached the base coat, I usually try using common household toothpaste. Take a bit of white toothpaste, apply it to a soft cloth, and gently rub the scratched area. Repeat this a few times before rinsing with water, as toothpaste contains fine abrasive particles that can fill in shallow marks. If the effect isn't noticeable, buying an automotive scratch repair pen to touch up the color usually does the trick for around a few dozen yuan. Be careful not to apply too much pressure to avoid worsening the damage. For moderate scratches where the metal base is visible, it's best not to handle it yourself—take it to a professional repair shop for spray painting to prevent rust. Deep scratches are even more hazardous, as exposed metal can corrode the car body, so they require immediate professional attention. For regular maintenance, I recommend periodic waxing or applying a protective paint protection film to reduce the risk of minor scrapes and bumps. In short, addressing scratches based on their severity is the most practical approach.
