Bad PDR (Paintless Dent Removal)
Bad pdr is when the dent is left with lots of highs and lows in the dent causing a textured look. Being that it is not invisible or back to factory.
Bumpy or sharp pushed out marks are signs of bad pdr. Also pdr technicians shouldn’t drill holes, if they do it would be in a safe, inconspicuous place. Which then must be treated and sealed properly.
