Car body damage can be very different. Therefore, the repair rules in each individual case should be individual, most suitable for this damage. In this case, the possibilities of straightening damaged panels are used to the maximum. It is necessary to avoid thermal effects on the metal, if possible, so as not to violate the factory welding and anti-corrosion protection of the body. In many cases, it is necessary to remove the front parts to determine the damage locations, straighten or check the frame. In cases of significant body damage, it is recommended to remove all easily removable internal trim parts to facilitate measurement, control and installation of hydraulic or screw jacks to eliminate distortions and damage to the body. Straightening restores the original linear dimensions and locations of load-bearing elements, windshield, hood openings, tailgate.
The protrusion of the front surfaces and removable parts relative to adjacent ones is achieved by adjusting or adjusting them.
