Fiberglass roof coating/sealant

What do y'all recommend for coating on my fiberglass roof? It's 8 years old and this year I can see the fiberglass somewhat glistening while on the roof.

I have a 5 year old GT that is showing the same signs. I have wondered what would be best to use as well. On another thread someone uses a 3M fiberglass boat/RV wax. I have never tried it. Hope others have ideas for us.

don't put a wax on your roof you will need to walk on it to wash it no?

Mine is 9 years old and still looks good, are you saying you are seeing the fibers coming through?

Yes, well sort of. I see the beginning of the glass fibers starting to glisten. Or show through

Not really a concern. The roof on ours is patterned and not smooth. I wax mine with a wax that has a UV protectant and it's not slippery at all.

My Fiberglass roof was showing signs of severe degradation last winter, such that I had to cover it with a tarp to prevent water ingress. The fglass was cracked with a lot of short spider cracks which were only apparent when you looked at it with a magnifying glass. The roof is 10 yrs old.
I bit the bullet and ordered "Roof Magic" on line. It came as a 6 gallon kit and in the spring over 2 days I painted the roof. It looks great and there are no more leaks.

In my opinion, the fiberglass roof material is too thin and its just a question of when it will fail. I cleaned my roof every spring and kept up with the caulk, but the caulk did not fail, the fiberglass did.
