I wanted to strip the firewall of my car, but didn't want to carry the body over to the outside sandblasting area, so I tried some non-woven paint stripping discs that mount in the common type of 4-1/2" angle grinder that has a 7/8" arbor, like in this picture. I had never tried this kind of stripper disc in a high-speed angle grinder before. I had used the kind that mount in a electric drill, but was not too impressed with those, I think because drills operate a too low a speed and you can't control the disc the way you can in an angle grinder. These discs do seem to work very well, and I am quite happy with them when stripping flat surfaces like my firewall, but they don't get into the nooks and crannies the way sandblasting does.
