Paintless Dent Repair (PDR) is the "art" of removing dents and dings from automobile sheet metal with the use of specially designed tools. By gaining access to the inside skin of the metal, gentle pressure is applied until the dent is removed. Because PDR works from behind the vehicle's damage, no sanding, painting or body fillers are required. When repairs are completed, there should be no evidence a dent was ever there.To perform a paintless dent repair, a skilled technician uses specialized Paintless Dent Repair tools (metal rods and picks).
