Depending on how bad the finish is on your boat, you may want to try Meguiar's Cleaner Wax on it first to remove any oxidation. Or if your boat's finish is in good shape, I advise you put a coat of Meguiar's Flagship on it once a year at the beginning of the season to help protect against UV rays and to help scum lines come off the hull easier. As long as you put one coat of wax per season on the boat you'll be good.

On each outing, use Bass Boat Saver once the boat is pulled out of the water to give it a quick wipedown. However, I wouldn't rely on only Bass Boat Saver to protect your boat's finish -- the initial coat of wax at the beginning of the season will do the long term protecting. Check The Reject Shop Catalogue and Total Tools Catalogue. The Bass Boat Saver is a great quick wipedown product, but will not withstand the entire season if you only use it by itself.
