Looking for an easy to apply wax / protection for the all-fiberglass roof on our motorcoach. Got it washed and cleaned up with new lap sealant and Enternabond tape on some of the seams, and now ready to apply some protection. Now I need something to protect the roof and stop the oxidation that causes the white-streaks down the side when it rains. A lot of owners use Zep Floor Wax and I just can't bring myself to do it (plus I've heard it is a nightmare to remove and can yellow in heavy sun). Another owner told me he used a 1 gallon jug of Optimum Car Wax https://www.autogeek.net/opcarwa1ga.html, put it on with a mop, and 9 months later still looked great and beaded the water off. Any other recommendations?
