The most vulnerable part of all car exterior parts is the front and rear bumpers. If the bumper is severely deformed or broken, it can only be replaced. However, under normal circumstances, if the bumper is only slightly deformed or cracks appear, there are ways to repair it without replacing it.
1. First remove the bumper and confirm the position where it needs to be repaired.
2. Heat the back of the crack with a plastic welding gun.
3. While heating the plastic electrode, move along the crack.
4. After the welding is completed, the temperature can be reduced to complete the repair.
