I was surprised that regular old Minwax Helmsman Spar Urethane did as well as it did. I would have thought there was some little know or only-known-to-hardcore-boat-guys super UV resistant product out there.

Looks like Helmsman, Benjamin Moore 440 spar or automotive clear coat are the way to go if we want a hard glossy clear finish. There is another productive heard of though that's more like an oil finish...I just can't remember the name right now though. If I think of it I'll post it later.
