Perhaps David will back me up here, but after reading the last few posts I'm going to have to recommend Aurora's products a little more strongly. I've been using them for the last few years and have no yellowing whatsoever. Aurora likes to state that since wax is yellow to begin with, that's what turns a boat yellow. Thus, none of their products contain wax. Once a year I use a deck brush to apply Boat Scrub to the decks and then follow it up with two coats of Sure Step (again, using a deck brush). That's the easy part. I then polish the rest of the boat with Boat Shine. I do it by hand, but it could be done with a buffer. My boat shines for the season and beads water into the next. Granted, she's out in the elements 365 in MD, so the results might not be a good further south with just one application.
