Sheet metal repair is to repair the deformed part of automobile metal shell. If the car is hit by a pit, it can be restored to its original appearance by sheet metal repair, and then the original paint effect can be restored by spraying special paint.
The potholes in the car also need sheet metal repair. First pull out the pit with sheet metal, then scrape off the dust from the sheet metal, then polish the surface of the car, and finally paint and polish it.
If the damaged paint part has lines, you can start with lines. What if it's just a pit? You can pull from the edge to the middle bit by bit. If it is a big pit, you can roughly pull it out first and then repair it slowly. You can't pull it out at once when you pull it out, or the effect will be swollen. If it's just a simple pit, you can pull it bit by bit from the side. If the iron sheet of the car is too soft, you can tie it tightly with a fire stick, and you can't beat it with a hammer, which will damage the car.
The first thing to look at is the material of the door. Plastic doors and aluminum doors cannot be repaired by sheet metal, and need to be repaired by 4 specialty stores. @20 19
