I'm getting ready to compound my 290 for the first time and seems the only thing I can't wrap my mind around is how to effectively hit all the smaller areas with say something like a Dewalt DW849 polisher. Seems that most use at least a 7" polisher, but on my 290 all the flat surfaces above the rub rail are broken up into 3 - 6 inch tall sections. I was thinking of maybe trying to find a smaller polisher, maybe a 5". I know it would take longer for below rub rail, but I think it would make the job easier for above. Any advice?
