Back in the day( 1979) I was a "Tidy Car" dealer and did paint sealants, pin striping, detailing ,etc. We used the CYCLO buffer, it had a differnet name, but was the same unit. I still have one that am going to refurbish. It needs a new cord, grease, etc. but still works. I need to get new pads,etc. for it. It always worked very well, you just have to be careful around the windshield, tight places, etc. as it can get caught and cause small damage if not used properly. As to the polishing compounds, polishes, etc. I have not used very many. I would also be interested in what everyone thinks. I still had a couple of cans of the "TIDY CAR" sealants that were great at the time, but I'm sure that there are better products available now.
