Can the car dent be repaired?

Car dent repair can be solved by pulling and pulling and strong magnetic absorption. First, when the depression is deep and large, you can use the pull-out method, heat the glue gun, apply the melted glue stick to the suction cup, and pull it out. Second, when the depression area is not very large, strong magnetism can be used to suck out the depression with the optical lever dynamic principle.

The main reason is that the depression without paint loss can be repaired as before, the hail pit can be perfectly repaired, and the corners and AB columns are difficult to repair. Automobile dent repair diagram Automobile dent repair technology The repair of dents is based on the principles of optics, physics and mechanics, and uses the lever principle to make dents of different sizes appear on the car body due to various external reasons.

The repair method of car bumps is as follows: the first method: heat with hot water and flatten the concave part by yourself. First, boil a large bucket of hot water, and then heat the hot water to the concave place with a spoon.

Second, the treatment of the machine is to suck out the concave part from the outside with the car dent machine, and then knock it back with a rubber hammer. The part of the tendon can basically be repaired and operated in front of the owner.

How to repair car pits

1. The repair methods of car pits include thermal expansion repair method, 4S store repair, suction cup repair, and rubber stick repair. Thermal expansion repair method: If the place where the bump is made of plastic such as the bumper, it can be heated by splashing boiling water or heating with a hair dryer to suck back the concave place through the characteristics of thermal expansion.

2. The repair methods for the car hitting a small pothole include thermal expansion repair, go to the 4S store to repair, and use a suction cup to repair. Thermal expansion repair method: If the place where the bump is made of plastic such as the bumper, it can be heated by splashing boiling water or heating with a hair dryer to suck back the concave place through the characteristics of thermal expansion.

3. There are two ways to repair car pits, one is sheet metal repair and the other is dent repair.Sheet metal repair is to repair the deformed part of the metal shell of the car.

4. The repair method of the car is as follows: the first method: heat it with hot water and flatten the concave part by yourself. First, boil a large bucket of hot water, and then heat the hot water to the concave place with a spoon. After the plastic is heated to a certain extent, push it out by hand on the back of the concave surface until the concave part protrudes and recovers.
