You may have misunderstandings about paint-free car dent repair. Let me introduce some science here. The so-called car dent repair technology is also called micro-sheet metal, and sometimes it is also called traceless and non-destructive technology, etc. Anyway, It means that there is no need to destroy the original car paint to repair the car body concave surface. The principle is actually very simple. It is based on optics and mechanics, and uses the lever principle to slowly restore the dents of different depths to the original appearance (similar to that of a mobile phone) Restore factory settings), you can see it clearly by looking at the picture below.

Everyone thinks this technology is very simple. It is indeed easy to get into the industry, but it is really difficult to do it well. The market is still in a downturn nationwide. Many people do not understand this technology and still rely on it. There are many people who are good at painting gourds, and the early closed repairs have made this industry very limited. There are only a handful of car dent repair technicians who can truly be called masters in the country. After all, each master has his own requirements. Different, the repair effect may be good or bad. Really repairing it to the same as the original car paint is not a matter of time, but experience and understanding. Therefore, when repairing, you must choose a well-known local car dent repair shop, a small shop, a backpacker, and a genuine repair shop.
