The dent in the car skirt can be supported by wood. The body shell is mostly made of metal materials, such as steel plate, aluminum alloy and plastic. Different bodies and different positions are made of different materials. These materials are very malleable and dents can be repaired seamlessly. The paint of the original car consists of four layers, namely electrophoresis layer, middle coating layer, colored paint layer and varnish layer from inside to outside.

Sag repair method

It is necessary to stretch the ribs, then reshape the side skirt, grind it after reshaping, then putty the side skirt, then grind it flat, then spray particle glue, and finally spray paint. Pay attention to symmetry when painting.

Generally dents are corrected by sheet metal, which will not cause much damage to the car in theory, but as long as the car structure is deformed, the strength is not as good as the original.
