Fiberglass roof coating

[Travelwrench]

I have a fiberglass roof and I get white streaks when it rains. I have used the mop n glow which works but I am looking for something more permanent. Can I coat the whole roof with Dicor fiberglass roof coating. Also I did my sons Mobile home a few years back with a product from lowes was like a white coating went on thick can a person use that on the RV? I believe it is BLACK JACK Roof-Gard 700 White Elastomeric, they also make a 10yr.

I used Sher-Cryl HPA Acrylic by Sherwin-Williams with great results.
It goes on as easy as rolling on a latex paint with performance characteristics similar to a urethane.
I put mine on four years ago, it has eliminated all streaking and is easy to keep clean.
Caution: surface preparation is critical for long term performance. You must remove all the white chalk prior to coating.
Just let me know if you are interested in a more detailed description
