Car maintenance should avoid "pits", but how to prevent them?

If you want to talk about fault prevention, when the vehicle reaches a certain mileage, you must remember to replace the relevant weary car parts, and at least remember to bring spare supplies with the car.

How to repair car pits

The repair methods of car pits include thermal expansion repair, repair at 4S store, repair with suction cups, and repair with glue sticks. 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.

The repair methods for the car hitting a small pothole include thermal expansion repair, repair at the 4S store, and repair with a suction cup.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.

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.

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. 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.

Sheet metal repair Whether it is a large or a small depression, it can be used to repair. Although sheet metal is expensive to repair, the effect is the best.The owner of the sheet metal project generally cannot complete it by himself, and needs to go to the car repair shop to carry it out.

How to suck out the pits in the car

1. You can also buy a car dent repairer by yourself. It is a tool such as a hot melt glue gun, bridge structure suction device, etc., to suck the car body with a suction cup, and the position of the body depression through pulling force. Suck it out. If the car hits a pothole, it can be repaired by traditional sheet metal.

2. Put the hair dryer in the hot air gear and blow it to the part of the car's dent with the air outlet. It should be noted that the distance should not be too close. If it is close, the car paint will melt due to the high temperature, and it should not be too far away. If it is far away, it cannot achieve the effect of repair. The distance of 15 centim is the best.

3. The first step is to find that a small piece of the surface of the car has been concave, and then continue to the next step.The second step is to prepare a pot of hot water first. Step three, pour the hot water inside on the sunken surface of the car. Step 4. After completion, prepare a toilet bowl.

4. Briefly talk about its principle. Through hot melt glue gun, bridge structure suction puller and other tools, the car body is adsorbed with a suction cup, and then the concave position of the car body is sucked out through the principle of tensile force. Although the operation is simple and you can do it yourself, the completeness after repair is not as good as the traditional sheet metal effect.
