the guys who dont know what their doing, dont have the right equipment, are lazy or dont care drill holes, you should be able to get any dent out from the back side or by using glue pullers from the top side...
it's against insurance policy for a PDR tech to drill holes in ANY panel, if they do they are required to replace and refinish the panel (s) and blend adjacent panels...
and they really cant do anything larger than a half dollar in diameter, with VERY few exceptions...so if it's bigger than that I probably wouldn't go PDR, in fact they will probably turn you away...
