Rob: If you want to get a machine buffer that is almost idiot-proof, buy a Random Orbital Polisher like this one: Bosch PEX400AE Random Orbital Polisher From www.finalinspection.com.au These are not as dangerous as a rotary buffer because the head moves in an eccentric motion and doesn't generate as much heat between the pad and paint. So it's almost impossible to burn your paint. I have the Festool RO from that website and I absolutely love it. You can use wool pads, but not steel wool.. unless you want to scratch your paint off, haha. Wool pads on an orbital buffer are used for heavy cutting.
