The repair of the side skirt has a great relationship with the side skirt material used in the car body. If it is made of plastic, repair is the best. You can knock it carefully with a towel wrapped in a small hammer and restore it to its original state. If it is iron metal, you can only drive to the repair shop to paint the car body. If it is aluminum alloy, it must be replaced if it can't be repaired. Repair method of automobile skirt depression: 1. The side skirt depression can be sucked by a suction cup. With the help of the difference of internal and external atmospheric pressure, it is adsorbed on the object, which has a very large tearing force; 2. We can use such a small suction cup to repair the small dent in the car door and suck the suction cup in the dent. If the dent is large, you can also prepare a few more and absorb them evenly in the center of the dent. Then you can pull it out with a tool. You can do it without tools, but you need skilled strength, otherwise the depression is likely to become prominent. There is a special bridge suction rod on the internet to repair the sag, which can suck the sol gasket we put on, and then turn the nut until the sag becomes flat; If you don't want to do it yourself, then we can give it to the repair shop outside. They have a dent repair technology, also called light sheet metal. However, I think the dent repair technology is not much different from our own. Basically, we suck out the dent with a sucker, then put a hook on the back of the dent area, then gently push it out, and finally treat the protruding part with a rubber hammer.
