Car body dent repair (Mazda 6 GG)

When repairing dents, the primary task is to pull out the deformed surface to bring it to the initial level. Attempts to achieve a 100% match to the original make no sense, since this is still impossible due to the damage to the internal structure of the body panel metal upon impact. The optimal solution is to bring the concave surface to a level approximately 3 mm below the surface of the surrounding undamaged section of the body panel. If the dent is not deep, its complete pullout makes no sense at all.

In cases where the concave area can be reached from the back of the panel, you should try to straighten the dent from the inside by hitting it with a hammer with a soft head (rubber, plastic). When tapping out the dent, press a wooden mallet firmly against its face to dampen the impact impulse and avoid excessive outward bending of the deformed metal of the panel.

If the dent is on a two-layer section of the panel or access to it from the back is impossible for some other reason, you should use a different pulling method. Make several small holes in the concave section of the panel, trying to make sure that they are in the deepest areas of the dent. Then screw long screws into the holes, leaving their heads sticking out enough so that you can grab them with pliers. Now start pulling the dent out with pliers by the screws.

The next stage of dent treatment involves removing any remaining paint from the damaged surface and an area of approximately 3 cm around it. This work is best done with a wire attachment or a stripping disc mounted in the chuck of an electric drill, but manual sanding is equally effective. The final stage of preparation for puttying is scratching the dent metal, which has been cleaned of paint, with a screwdriver or a broken file, or drilling small holes in it to ensure maximum adhesion of the putty to the metal surface. Then you can proceed to the puttying and painting procedures.
