You would think someone would come up with a product that would seal the fiberglass and stop the oxidation. Anyone have any luck with this issue

I cleaned mine then applied 303 never had a problem since and 303 is easy to put on.

What type of roller did you use? Foam or fabric?

I used a foam roller. One of the small diameter ones. Also used a 1” term brush around A/Cs etc

Chargerman- I used a degreaser first then sanded the entire roof with 100 grit paper,then power washed the roof. There are still some spots that have a slight sheen. Did you experience the same thing? Just want to make sure I don't have any issues with application. Thanks

I think you will be just fine. Can’t recall if I had a sheen but the steps you have taken so far are good. Remember to mask the perimeter a little bit below the factory line so that the new paint overlaps the clear coat a bit to seal that edge. It will help to prevent future clearcoat lifting.
