1, traceless repair is cheaper;
2. It takes less time to repair the depression, leaving no trace;
3. The original car paint can be retained by seamless repair of the dent.
Although the advantages are outstanding, seamless repair of dents is not what you want to do. As mentioned earlier, the paint is not damaged. In addition, if the car paint of the concave part has been painted, or it is close to the edge of the body sheet metal, and the rear fender of some models is double-layered, these are not suitable for the seamless repair technology of the concave part.
Traceless repair method
The most common seamless repair of 1. depression is to use hooks of different specifications and a whole flat hammer. Tools may not be important, which tests the repair skills of technicians.
2. Put your hand into the back of the recessed area with the help of the hook, and then push it out slowly. If the recessed position is inconvenient to operate, it may be necessary to remove the body parts at the corresponding position.
3. Then tap the protruding part continuously with the whole flat hammer, which will make the dent disappear as far as possible.
4. Another method is to pull out the depression with hot melt adhesive, but this method is more troublesome because it is easy to leave residual glue, and it is necessary to do a good job of removing glue. After the depression is pulled out, as in the first method, slowly restore the paint with the whole flat hammer.
