Will you have a headache because of a small dent in the car door, and there is nothing you can do? In fact, the small dent in the car door is easy to repair, that is, using a suction cup. Next, let's take a look at how the suction cup in the door depression is repaired. Many people have this kind of sucker at home. It uses the difference of internal and external atmospheric pressure to adsorb on the object, and has a very great breaking force. Then, we can use this small sucker to repair the small dent in the door and suck the sucker 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. It is possible without tools, but it requires skilled strength, otherwise the depression is likely to become prominent. There is a bridge suction rod specially designed to repair the sag on the Internet, 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, the dent repair technology is actually similar to our own. It sucks out the dent with a sucker, then inserts the hook into the back of the dent area and pushes it out slowly. Finally, the protruding part is treated with a rubber hammer. Automobile dent repair technology determines the price according to the difficulty, area and sharpness of dent repair. The sharper the dent, the more difficult it is to repair, and the price will be more than several hundred yuan. For example, the price of an egg-shaped depression is generally around 150 yuan. Repairing dents on car doors can save us money and time, but not all dents can be repaired. As long as the paint does not come off and the dent is not deep, then the dent is easier to handle.
