RV Fiberglass Roof Wax / Protection Products?

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?

This post is rather old, but I have the same question! Any answers?

I don't think you're going to get a reply until you go into how much work it is to apply a product to the roof and how often you plan on applying. Too many variables to make a suggestion.

McKee’s Hydro Blue sounds good on paper... But I’ve seen some vids on youtube that show the beadings completely gone within just 2 weeks. I dunno.

HydroSilex with the foam cannon would be super fast and easy to apply.
Also carPro has a soapy wash that leaves behind protection. Forget the name of it. You just wash the roof and rinse off.
