I have a Minkota 9227 buffer with 7 and 9 inch wheels. I bought it for work on compounding the hull primarily per a recommendation from Mainsail. It has an easi;y adjustable control for the rpm and erogonmically is easy on the hands.
We redid our cockpit table 3 years ago. Stripped it with Circa 1850 varnish stripper before sanding in an outside garage using water color paint brushes to get into the small areas like the cup holders. I wound up using a dremel for the areas I couldnt get the buffer into.

I did go for the eppifanes gloss varnish and a clear poly coat on top. After 3 years still looks like the dat we did it. Shows you how much the UV destrpyed things as ours is under the bimini at the steering pedestal protected.
