I have to tell you, this technology has it's place. If it is not PDR, I don't care so much because I am not in that business anyway.
I have lost interest for the most part. It is a NOISY MUTHA that is for sure. It has been hard to pull the thing out in the shop, people want to choke me.
But it has some uses. Just the other day I had a 2007 Toyota Corolla with a dent in the roof. I dropped the rear of the head liner and was able to reach my hand with a die grinder and one of these Dominator wheels on it. I massaged the dent out needing only a VERY thin skim coat of polyester putty. I couldn't have done this anyother way other than dropping the head liner out completely. It worked like a charm in this particular application.
