If you get nothing else out of this thread, it should be that you shouldn't build fuel tanks out of epoxy, now that we have vinyl ester. Yes, you can slosh the tank and probably get good results, but it's another step, and you have to do it right. But if you use vinyl ester resin (Aircraft Spruce sells it) you're not likely to ever have a problem with it.
Keep in mind that once promoted (and that's how AS&S sells it), the shelf life will only be 2-3 months, so this is not something you want to order in advance. And it will stink up your house for days or weeks, so try to do this outside. And don't do it in high temperatures, as the cure time is reduced to minutes. Catalyzing small quantities is measured in a very few drops, so one drop too many and you might have five minutes of working time, and that's hard to accomplish anything that involves wetting out fabric. On the other hand, I built my last wing tank in my hangar at over 100F, and I finished it in a day! That's another reason industry likes this stuff...productivity! Oh, and wear safety glasses when adding catalyst. One drop of the MEKP catalyst will blind you within minutes, if not seconds...
