Anyone had any experience with a "friction system" for taking out dents?
Not the "paintless dent removal" where they take care of dings, but a 7"-9" set of discs that go on a regular grinder. Photos showed some fairly large hammer dent in a fender... The dent is gone over with the discs and then water is poured on the area. Then you repeat the process until the dent is gone. It's supposed to be a way to get away from Bondo. I haven't found much info on it and was wondering if anyone has tried it.
Thanks
