Polisher/buffer selection

I've browsed the old discussions on gelcoat maintenance to learn what
I can before developing a maintenance routine of my own, for my
recently acquired V2C. One thing not yet clear to me is the best way to
use/apply 3M's Finesse-It II, which seems to be the consensus
cleaner/polisher compound: With a high speed (~3000 rpm) polisher, or
something slower? With random orbit or fixed rotary? (Does Finesse-It
II require the generation of heat to do its thing?)

There seems to be a broad range of prices (from ~$30 for a Ryobi 10"
orbital polisher at Home Depot, to $190 for a DeWalt DW849 polisher,
mail order), so this is an investment I want to get right the first
time.

Advance thanks
