Will Dicor Sealant work on fiberglass roof?

Hello fellow National RV owners, I have a question regarding roof maintenance. One of the selling features of National RV's was the fact that the company used a fiberglass roof rather than EPDM.
I'm curious to find out if Dicor Self-Leveling Sealant will work on this fiberglass roof material, or if a different sealant would be better.
In particular, I'm referring to resealing the front and rear caps, antennas, the ceiling vents, shower skylight, and all other roof penetrations.
It looks like most of the sealant on my 07 Sea Breeze is factory original and I have no idea what the factory used.
Thanks for your suggestions as to what to use and as important, what didn't work as well.

Dicor works fine. Used it on all three fiberglass roofs of my RVs.

The factory used White Dicor on all roof items. On my 2008 Dolphin they ran a strip of Eternabond roof tape over the joint of the front and rear caps to the main roof. I believe where the roof curves down and joins the gutters/side walls they used Pro-Flex.

Dicor works fine. i put Eternalbond roof tape on my front and rear seals about 5 years ago. No issues since.
