General automobile is mainly made of metal sheet metal, engineering plastics, glass, rubber and other materials, which are divided into multiple regions and plates, and the whole vehicle is assembled by welding. In the event of a collision, if the appearance is only uneven or damaged, according to the degree of damage, you can choose strategies such as repair or partial replacement, which needs to be carried out in a professional automobile maintenance and beauty shop.

If the collision is serious, the existing car body structural parts will be deformed or damaged in appearance, the maintenance cost will increase sharply, and the damaged parts will even lose the value of maintenance and repair, so you can choose to scrap them directly.
