No offense...but been in a coastal environment all my life and have worked with fiberglass since I was an infant. It's actually wax...literally wax that comes to the surface. Never heard it called blush.

Not true. Seals and caulk need to be inspected at least yearly or better yet, every 6 months not every couple years. A couple years wait can result in water leaks and nasty things going on inside the walls.
I'll take a glass roof over rubber anyday. The rubber membrane is thin and can tear easily from just a branch dragging over it. Glass don't tear and a repair is as easy as some bondo.
Having said that, my preferred choice is a one piece aluminum sheet roof. Will last forever.
I keep my RV's at least 10 years, sometimes longer. My last one had an aluminum roof that looked as good as the day it was new (12 years old) and my new one is glass, 3 years now and looks fine.

Assuming it is standard thickness fiberglass and not just a thin 'glass material like Filon affixed with contact cement.
Fiberglass boat decks/roofs are almost always multiple layers of cloth (many styles and thicknesses). The substrate/"core" is wetted and the first layer applied. More slow hardening resin is applied so that the cloth is thoroughly wetted out and all air bubles can be worked out. Before the resin starts to harden, a second layer is applied, wetted and a third. The reason this layers are done at the same time is because epoxy resin leaves a film (called "blush") after curing which must be sanded off before additional layer of resin and cloth are applied.

Not at all, any competent boat shop can fix a fiberglass roof.
