When a small piece of paint is thrown from the car by a stone, it can be repaired with sheet metal and spray paint. Fill the pit with putty first, and then repaint it at the repaired position. At present, this repair method is mature and widely used in the market, but the process is relatively complicated and may be different from the original car paint.
Car owners can also use seamless repair methods, also known as micro-sheet metal. It can repair the dent position without destroying the original car paint. This principle is not very complicated. On the basis of optics and mechanics, it uses the lever principle to knock the dent and restore it to its original appearance.
No matter whether the owner chooses sheet metal maintenance or seamless maintenance, he needs to go to the regular maintenance department to ensure the maintenance effect. Some small repair departments may fail the test, which will cause secondary damage to the vehicle.
