1. It is indeed credible and feasible to repair the car body depression with hot water. It takes a process to continuously pour hot water into the concave part of the car body. When the depression reaches a certain heat, the material will soften, and the depression with a larger area will automatically change and gradually become smaller. At this time, if it can be pushed out from the inside, the depression can be restored;
It is not so magical to repair the dent in the car body with hot water. This principle is just like our soldier ball. If the soldier's ball is concave, putting it in hot water can make the ball collide. However, hot water is not suitable in all cases. If you encounter an iron or aluminum car dent, this method will not work. It is obviously not feasible to repair the deformed metal materials with boiling water. Different repair methods should be selected according to the deformation degree, such as automotive sheet metal plastic molding machine. This method is not feasible if there are cracks in the paint surface of the car body and the paint surface falls off.
In fact, you can try to repair the dent in the car door yourself. You can buy such a set of dent 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 for the big depression, and the larger the gasket, 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.
4. Align the hole in the middle of the traction bridge with the attached gasket, put the nut on the gasket screw and tighten it, then turn the nut until the depression is flat. After the repair is completed, remove the tools, then spray alcohol on the residual glue on the car body, and finally clean it up with a spatula;
If you don't trust your hands-on ability, you'd better give it to the outside repair shop. Generally speaking, they call the repair of dents in the car body "light sheet metal". Actually, it's similar to the principle of doing it ourselves. They all suck out the dents with tools, then put their hands behind the dents with hooks, then push them out slowly, and finally treat the protruding parts with rubber hammers.
