technically I wax my 32' 5er every time I wash it as I use Turtle Zip Wax (Wash & wax), all that does is maintain some protection. To get oxidation off requires some physical labor, either by hand or a buffing wheel.
I use Optimum no rinse wash and wax as well. The Protect All gets sprayed on(its a thick consistency not like a spray wax which is similar to a detailer spray). This gets wiped off with microfiber. It cleans, polishes, waxes and protects. Use it 2-3 times per year and the camper beads and shines all year long. :)
