The deformation of the sheet metal will definitely have an impact on the car. It must be polished with a setting machine, which will affect the thickness of the sheet metal, and the anti-rust 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 water is not completely dry. In short, a few years later, corrosion began from the inside.

The iron parts inside the car body will change after sheet metal, which is very easy to rust and corrode, especially the safety factors of beams and columns will become lower. Personally, I think it is best to do anti-corrosion or painting treatment inside and outside after sheet metal.

The effects of sheet metal maintenance on automobiles are as follows:

1. When the vehicle passes through the sheet metal, the external galvanized layer will be crushed. If the heating process is applied in the sheet metal process, the metal material will be annealed and the strength and hardness of the metal will be reduced. If there is a collision afterwards, it is difficult to ensure the safety of the occupants in the car;

2. When the vehicle passes through the sheet metal, because the metal passes through the sheet metal, if the repair is not professional enough, the exterior is easy to be uneven, and cracks and depressions will appear after a long time, which will affect the beauty of the vehicle;

3. Whether it is sheet metal or painting the whole car, it will have an impact on the vehicle's preservation rate, because your car is not the original paint, and repainting will not achieve the original effect anyway.
