than 2500rpm. I use the Autosol as a rub on, work pretty good. The white rouge is wheen buff addition that works pretty well in that instance but not as a rub on. White rouge is very chalky and liquifies once it hits the wheel and melts to the buff. At that point you let the buff cool and the rouge to stick to the buff. About 20 minutes later you can take that buff and begin to buff out the item. A whole buff full of white rouge usually gets about 8sq inches in diameter, if I had to guess.
