Pit repair is an automobile pit repair technology that does not destroy the original car paint. It is said that there are two forms of treatment:

One is manual processing. It is said that after disassembly, the pit was pried out with a special hook, then knocked back with a rubber hammer and leveled with light. This treatment has basically no damage to the paint surface, but the edges and ribs cannot be treated, and more masters are unwilling to show them to the owners during construction;

One is the processing of the machine. It is said that the concave part was sucked out by the machine and then knocked back with a rubber hammer. The tendon part can basically be repaired and operated in front of the owner.

If the depression cannot be repaired, the problem can only be solved by sheet metal painting.
