Fuelproofing
Rajul has a good point there.
The Z-Poxy finishing resin from Pacer works really good.
With other 30 or 45 min. epoxys you get millions of tiny air bubbles when you mix or thin it. The Z-Poxy for some reason mixes and thins clear as water and dries really nice, hard and transparent.
I use it pretty exclusively for glassing and fuel proofing and have always been happy with the results.
