1. Traceless repair: As the name implies, dents can be repaired without damaging the original car paint, and the construction process is relatively simple. The principle of seamless repair is to restore the dent on the surface of car paint to its original appearance by using the lever principle on the basis of mechanics and optics, and the price is relatively cheap. This repair method is recommended.
2. Sheet metal repair: scrape putty at the depression and level it, and then repaint the repaired part. This repair method is mature and widely used in the market, but the process is more troublesome and the price is slightly more expensive than seamless repair, and it will affect the maintenance rate of vehicles after sheet metal repair.
