Is there a trick to not burning these down to nubs? I figure it will take a dozen or so to do a car, I usually buy 3 or 4 if I have a front end to do, one for a fender, two for a hood, etc etc. Sometimes I'd rather spend more on abrasives and not burn my arms out from using the grinder till my eyes fall out.
Yeah they do burn out quick. I think I went through about four of them and my car still isnt completely stripped yet.
I used it on a set of wheels I had. It worked good but just too messy for me. I like the norton discs best.
Use the 3M discs in a polisher, or something you can slow down to about 1400 RPM, they will last longer and still work well.
finally someone with sense! I have tried everything out there, the heavy duty cup brush is by far the way to go. I concur said Spock.
any kind of scotch bright pads dont last long on the end of a grinder,and gets expensive especially when doing a whole car.Paint stripper followed by a DA pad works just fine and by far the cheapest.No material loss thru using paint stripper.
i used an angle grinder with the knotted wire wheel as well. i did the majority of my f100 with it. it was loud and not a whole ton of fun, but it did get the job done. i will most likely follow it up with some sort of 3m abrasive disc to get things evened out and polished a bit better. i have fenders from different trucks on the front and rear. the rears turned out alot better because they were just in better shape. the fronts were a bit more beat so they had more filler/primer/ paint on them. im going to run the truck in bare metal, so an even "finish" would be good. ill try my best. i dislike using the air craft stripper too. i dont like the goopy mess. thanks for all the info on the 3m products. take care.
