Wanting to seal my fiberglass roof.

[QuigRig]

Hello All, I recently did some work on my fiberglass roof and noticed some cracks in the paint or whatever was used to seal the roof in the past. They are not in the fiberglass just the coating. It is a "Coachman top" and looks to be original from 1990. I believe that as it has badly faded paint that matches the van. My priority is waterproofing but if I can match the color of the van with whatever product is best that would be great also. The roof just has solar panels on top so I would not need a product that would need to be durable if I was on the roof a lot.
I was hoping someone has resealed their roof and has been happy with the way it has turned out and happy with the product they have used.
Any help will be greatly appreciated. I have done many things but resealing a fiberglass roof is not one of them.

Here’s a great thread to review…

I Raptor lined mine and color matched the Baja Tan paint. Worked out nice.

Thanks, Steve C.
I was thinking along the lines of EMPD butyl. Maybe that is more for motorhomes and trailers with seams.

The outer, smooth layer of fiberglass is called the "gel coat." If you do a web search for "gel coat crack repair" you'll probably get some useful info.
