I work for a detail company. The make us use the festool 125 its a rotex type sander. When you change the backing it can be transformed into a polisher. I don't like it to much. I have seen both tge rupes big foot and the polisher from adam's in action. I've only ever used the rotex and a rotary buffer. Can i have opions on which is the best buffer? I also have studied paul dalton who uses the rupes. Help please.
