Sheet metal repair has no harm to the car. Generally speaking, the deformation of sheet metal will definitely have an impact on the car. If you use a setting machine, you must polish it, which will affect the thickness of the sheet metal, and the antirust treatment behind the sheet metal surface will not be burned. Even if putty is scraped on the surface of sheet metal, its antirust strength is not as good as before. Another common putty is water mill. After water mill, the innermost moisture will not be completely dried.

Main processes of sheet metal processing: The main processes of sheet metal processing can be roughly divided into:

1: body disassembly;

2: body correction;

3: Physical repair.

The car is a high-precision whole. Moreover, electrical accessories and mechanical accessories should be attached to the corresponding positions of the car body with high precision and low error. Even the straightness and curvature of car paint (which greatly affects the beauty of car body) are highly dependent on the error value of car body sheet metal. Therefore, sheet metal body and its repair have become a purely manual work in the automobile industry without hard standards, automatic tools and intuitive teaching.
