Sharp dents are one of the few dents that most often cannot be removed via paintless dent repair. These dents occur along the body lines of the car and are often deeper than round dents. They are also tighter than round dents, making them harder to repair, especially if they are in a difficult spot.

PDR's success depends on the dent's size, depth, and location. Paint condition is also a factor. Paintless Dent Repair can usually repair dents up to the size of a grapefruit, while large dents typically require more traditional dent repair methods.

The so-called PDR technique (Paintless Dent Repair) is the less aggressive way to erase dents from vehicle sheet metal, as it doesn't involve using sandpaper, fillers or paints that reduce the value of the vehicle. Instead, the repair process is carried out with tools that won't adversely affect it.
