Dremel rotary tools are really intended for toy and hobby applications. Not enough power to do the job on all but the smallest automotive work. I have one that I use all the time in my model making but rarely take it out to the shop to work on cars. For small car jobs requiring portability, I use a small 1/4" air-powered grinder from Harbor Freight, about the size of the Dremel but many times the power and can modulate speed. Will easily handle 2" diameter buffs that would stall a Dremel. For off-the-car, serious polishing (recommended for stainless trim - that stuff is pretty hard and needs some serious power to do a good job) I use an old 3hp, 3600rpm, stand mounted, swimming pool pump motor. This can handle the 10" x 1" buffs without stalling and will quickly tackle everything from stainless trim to intake manifolds, to aluminum tranny cases without raising a sweat.
