If the paint falls off the body, it is recommended to paint the body. However, if the paint surface does not fall off and you are very concerned about the paint surface of the original car, you can try the paint-free car dent repair technology. The principle is actually very simple, that is, based on optics and mechanics, using the lever principle, the pits with different depths are slowly restored to the original appearance.

I'm sure many people have heard of repairing dents in car bodies with hot water. This method is reliable and feasible, but it has great limitations. If you encounter an iron or aluminum dent, this method will not work. For the repair of deformed metal materials, it is obviously not feasible to use boiling water. Different repair methods should be selected according to the deformation degree, such as automotive sheet metal plastic molding machine. This method is also not feasible if the paint surface of the car body cracks or falls off.

We can also buy a set of such sag repair tools online, which is not expensive, only a few tens of dollars. Clean up the concave part first, then put the special glue into the glue gun and plug in the power supply to preheat for about 7 minutes. Then choose the appropriate gasket, pay attention to the large gasket suitable for large depressions. The larger the washer, the greater the traction. Then use a glue gun to evenly coat the gasket with sol, quickly paste it to the concave position, and gently press it until the special glue is fixed.
