Dont be skeptical. PDR guys get paid really well because they can fix dents without upsetting factory paint. Some are hacks and want to drill holes in doors and plug them to get to the skin, but good ones are worth the price, which is usually substantially less than paint. Ask around after a hale storm, and you will find the PDR guy that does it right. My wife's uncle gets paid mega bucks to travel the US following storms to repair cars.
