Sealing Surface Cracks on a Fiberglass RV Roof

[Gyrophoenix]

Anyone have a recommendation for a specific brand of sealant to put on these surface cracks? There's no leakage, as the fiberglass is over 1/4 inch thick. But I'd like to seal them up anyway.

Thanks.

I would not use typical EPDM coatings over fiberglass. I would think new gelcoat or acrylic paint is a longer lasting solution.

I would not be afraid to coat with something like Henry's Tropi-cool on it, but something like Dicor Fiberglass Roof Coat (a high grade paint) is much easier. A gallon of the Dicor (or a similar marine deck paint) would do the job nicely. It will take you longer to clean the roof thoroughly than to paint it.

Are those really cracks? It looks like the roof has been scratched by something in two different directions.

RV Roof Magic will work great on fiberglass. And last a long time 18-20 years (1 coat).
