To those of you who have used 303 do you use it in addition to wax or as a substitute for wax? Thinking of getting some and trying it out. Sounds like good stuff.
We use it on our roof. After washing, we put a couple of coats off 303 on. We also use it on the graphics and other other non gel coat parts of our 5th wheel.
