How Does Paintless Dent Repair Work?
1. Direct leverage. Gaining access to the metal with direct force on the dent, from behind. This can be done behind your factory bracing, through sound dampening pad, and on body lines for a minor uncharge. This method traditionally requires the creation of access, which will be plugged and rust proofed once the job is complete. PDR is the preferred method of Dealerships and Auto Auctions because it doesn't cost as much and it's typically a faster repair for the technician.
2. Indirect leverage. Gaining access within the recess of a panel and using a bridge to affect the surface or skin of your vehicle. Typically this requires the removal and reinstallation of factory parts, such as inner door trim, headliners, or anything that might prevent access to the outer shell from behind.
3. Glue pulling. The process of pulling the surface of the damage with specially formulated hotmelt glue in conjunction with hardened plastic or metal tabs. Necessarily, the tech will choose the appropriate tab, type of glue, temperature of the glue, all based upon the climate, temperature, location, and type of alloys within each panel. Once the glue and tab are attached to the surface of the metal it is either lifted with a slide-hammer or a mini-lifter. Typically, a slide hammer shocks the metal with a very strict upward jab, while a mini-lifter provides a more direct and slower progress upwards. In the hands of a professional, this process is excellent for areas that cannot be reached with other methods.
Paintless Dent Repair is the science of removing dents by pushing or pulling on the factory finish, leaving the vehicle in its original state before the damage. This process stands in stark contrast to a body shop that uses fillers and paints to achieve the same results. An analogy of the from the m
