8.2.1.5. Repair of dents
At repair of dents a priority is the pulling of the deformed surface to initial level. It is impossible to achieve absolute compliance to the original in view of violation of internal structure of metal of the body panel at blow. Removal of a concave surface to level about 3 mm lower than the surface of the surrounding intact site of the panel of a body is optimum. If the dent not deep, a full pulling does not make sense.
In case to the concave site it is possible to reach from a reverse side of the panel, try to align a dent blows of the hammer with brisk of soft material from within (rubbers, plastic). Tapping a dent, densely press to its face the wooden hammer for clearing of a shock impulse in order to avoid an excessive flexure outside of the deformed panel metal.
If the dent was formed on the two-layer site of the panel or access to it from a reverse side is impossible for other reason, it is necessary to apply other technique of a pulling. Make several small openings in the concave site of the panel, trying that they appeared in the most buried areas of a dent. Then screw long self-tapping screws in openings, having left their heads sticking out so that it was possible to grasp them with passatizha. Then extend a dent nippers for screws.
At the following stage of processing of a dent remove from the damaged surface and on the site about 3 cm wide around it the remains of a paint and varnish covering. It is the best of all to perform this work by means of a wire nozzle or the cleanup disk established in an electric drill cartridge, however also manual processing by an emery paper is not less effective. The final stage of preparation for a shpaklevaniye is the protsarapyvaniye of the dent metal purified of paint the screw-driver or a fragment of a file or drilling in it small openings for ensuring the maximum adhesion of hard putty to the surface of metal. Further you pass to procedures of a shpaklevaniye and coloring.
