Roof sealing product recommendations for a fiberglass roof

I have a 40 country coach with a textured fiberglass roof that needs resealing. Im a do it yourselfer and looking for recommendations for a durable, UV resistant product that can be brushed or rolled on. Has anyone done this or is there a reasonably priced company in Fort Worth that does this?

I opted to use Rustoleum Topside fiberglass paint, cleaned/pressure washed the roof and did 2 coats. Time will tell how long it will last but so far I'm satisfied.

Maybe but ...

I think Winnebago uses Silicone on the roof around openings. I think sealing around the roof edge is different.

I used the Dicor fiberglass roof coating. One gallon was about $90 and gave me 2 coats on my 40 foot Magna. Satisfied with the results.

How to take care of a Winnebago Fiberglass Roof

There's usually always more to every story....
When you properly prep a Winnebago fiber glass roof to apply Dicor roof coating this silicone thing around openings is a non issue. Dicor Fiberglass roof coating is a wonderful product in so many ways. I'm a big fan of this YT channel that I found awhile back and he shows exactly what to do and how to do it.

I did this process to my Winnebago fiberglass roof years ago and I have zero issues with my roof.

You said "brush or roll", so I'm guessing you are talking about the roof membrane itself and not the seams and openings. So my first question would be why does your fiberglass ROOF material need sealing? Or is it just a cosmetic problem, e.g. oxidation or stains? If you want to re-paint the roof to make it new and shiny looking, I'd suggest Dicor Fiberglass Roofcoat or a marine deck paint, e.g. Rustoleum Topside.

If instead you need to repair leaky seams and around openings, most any flexible sealer (caulk) will do, e.g. Dicor Self-leveling, Geocel Proflex, or any window & door caulk found at a hardware of home store.

No leaks, just oxidation that results in white streaks down the windshield and sides when it rains. Dicor sounds like the way to go.

oxidation happens. a few years ago, i had the same streaking. also a couple of small hairline cracks. washed the roof well, scrubbed lightly with a scotch brite pad, rinsed and applied 2 coats of rustoleum top coat. we wash or mh twice a year, so i can inspect the roof. still looks great and no oxidation at this point. easy to apply with a 6 inch roller. mask off the roof edges with blue tape, mask off anything else you don't want paint on. a word of caution. do not roll your coating on so fast as to make the paint fly, because it will. it sticks to anything. take your time and apply the 2 coats and enjoy the results
