The fiberglass penthouse roof on my new old van is pretty weathered. It's covered in hundreds of hairline cracks, and there are a couple tiny spots where the gelcoat is completely gone. At some point someone covered it with some kind of liner material that is now cracked and coming off.
I've done a bunch of reading this evening about repairing penthouse fiberglass roofs here on the forum, and am forming a plan of attack. What does this sound like...?



Thanks for any advice from your experience!

- sand down the paint and clearcoat until the cracks are all gone
- cover small fiberglass holes with epoxy putty. Marine Tex, perhaps?
- roll on Flex Seal over entire top
