In the past, I've always used a boat wax on my fiberglass boat every spring. (Trewax Boat Past Wax) All I do is use a boat soap and some black streak remover to clean the hull and follow it up with the paste wax. This year I'm considering just using a car wax at less than half the price...Meguiar makes both a car and a boat wax and according to their car wax description it also contains UV inhibitors. Anybody else using just a car wax??
