Since I haven't done it yet, I can't tell you much about making a tank out of this stuff other than- you must use epoxy resin. As I understand it, polyester is not resistant to gasoline.
I have heard different things about layup plies in fiberglass tanks reacting to ethanol blends. Not sure if pre-lining them with ethanol safe 2 part helps. Anyone else have any info?

I just ordered a filler neck as I said in this thread and will start making a 2 part mold soon to try one. Hopefully I have my camera back to document the layup.
