2. There is no point in trying to restore the exact original shape, since the metal in the damaged area was stretched by the impact and cannot be restored to its exact original shape.
3. It is best to restore the surface so that the depth of the dent does not exceed 3 mm.
4. If the dent is not deep, there is no point in trying to bend it out at all.
5. If there is access to the back of the deformed surface, you can try to restore its shape using a soft-headed mallet.
6. In this case, apply a wooden block to the front surface of the body in order to accumulate the energy of the impacts and prevent the appearance of bulges.
If the dent is in an area of the body with a closing panel on the inside or something else makes this area inaccessible from the inside, the following method must be used.
1. Drill several small holes into the metal inside the dented area - especially in the deepest part.
2. Then screw long self-tapping screws into the holes until they are firmly seated in the metal.
3. Now the dent can be bent out by pulling on the screw heads with pliers.
4. The next step is to remove the paint from the damaged area, as well as the area a few inches around it, using a sanding pad or a wire brush attached to a drill.
5. If you don't have these tools, you can use sandpaper.
6. To complete the preparation for applying primer, scratch the metal surface with a screwdriver or the corner of a file, or drill small holes in the damaged area.
7. This will ensure good adhesion of the primer.
8. To complete the repair, follow the steps described in subsection 13.3.4.
