Some time ago, there was a video on the Internet, in which hot water was used to heat the car dent, and then the dent automatically recovered. Everyone thinks it's amazing. It turns out that car dents can be repaired in this way, so today we will talk about it.
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.
Repairing the dent in the car body with hot water is not so magical. 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 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 also not feasible if the paint surface of the car body cracks or 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, and the price is not expensive, just 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.
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 hand it over to the outside repair shop. Generally speaking, they call the concave repair of the car body "light sheet metal". Actually, it's similar to the principle of doing it ourselves. They all suck out the concave position with the help of tools, then reach into the back of the concave area with the help of hooks, then push it out slowly, and finally treat the convex part with a rubber hammer.
