I usually use a two part wax process in the spring, and then just use Bass Boat Saver to maintain it the rest of the year.

Bass Boat Saver is good stuff. It's a wax-as-you-dry product, best when applied while the boat is wet.

I usually order a gallon each year. Some guys go in together on the 5 gallon jug for the best deal.
