The inside layups went more or less according to plan. However, because I'll have ethanol in my fuel, I paid the extra bucks (lots of extra bucks) for ProSeal, which is supposedly proof against a range of alcohols and fuels. We'll see. It sure is expensive. It's also a hell of a mess - it's very thick, hard to mix, and hard to spread, even when heated. It's definitely not like micro - it doesn't spread smoothly and you end up with lots of little icicles and frosting tips. It cures to a rubber-like coating. We'll see!
