If the dent is serious, it is recommended to go to a professional garage or 4S shop for the best treatment. You can try to repair it from the inside and try not to cut the side skirt directly. As far as the later painting is concerned, the painting is sprayed on the whole skirt, and only partial spraying will have color difference.

Sheet metal is a simple sheet metal correction-putty-painting-paint surface treatment, which will not cause harm to the car in theory. Usually, there are some panels in the sheet metal. However, it still has an impact on sheet metal. After all, both steel and iron are not as strong as the original strength after structural deformation and repair.

Precautions for body panels and painting:

1. Before spraying, users must first check whether the spraying air pressure is normal and ensure that the filtration system is clean.

2. Check the air compressor and water-dust separator in the paint room to keep the paint hose clean.

3, spray gun, spray hose and paint mixing tank should be stored in a clean place.

4. Except dust removal with spray gun and sticky dust cloth, all other pre-spraying procedures should be completed outside the painting room.

5. In the painting room, only spraying and baking processes can be carried out, and only vehicles can open the door of the painting room. When you open the door, you must start the air circulation system during spraying to generate positive pressure to ensure that outdoor dust cannot enter the room.
