1 In order to avoid paint, it is required that the paint surface of the vehicle is undamaged and can be repaired under the original paint condition. The repair method is to suck the pit by pulling out the inner roof. The method and the strength of the hand are all based on experience. Glue the pattern on the concave part with hot melt adhesive and pull it out hard to achieve the repair without hurting the paint surface.
It needs to be repaired with paint. If the paint surface has been damaged, there is no need for nondestructive repair. Because of the high labor intensity and natural cost of nondestructive repair, it is necessary to polish off the paint on the surface of the deformed part with a grinding wheel, and then pull it out by spot welding with a setting machine. After the repair is successful, paint it. So you can't keep the original car paint.
