Fiberglass roof oxidation issue

Has anyone found a good product that once you remove the oxidation (caused by the suns UV rays) and apply the product, the fiberglass roof will no longer oxidize? Or a PRODUCT that has, at minimum, at 40 SPF to be applied periodically to the roof to keep the oxidation at bay?
Thank you all in advance.

    I used Bus Kote. A diy product and top notch.
    Used on a Trek with fiber glass roof.

    Aerospace Protectant 303 has SPF 40. Spray on, buff out. I've used it for a couple years now on a 2002 Itasca Sunrise that we bought used. Must have been in lots of sun as the entire coach had lots of oxidation. Very labor intense, but has made a huge difference in the look of the coach. I've applied it to the entire coach 3 to 4 times a year.

    A good quality fiberglass wax/polish will give protection, but like everything else, it must be reapplied frequently and the sun will always win in the end!
