I got some Redkote and some National Tank Sealer(Por 15 stuff) and used them on a couple of test pieces of metal. Tossed 'em in a gallon jug of gas about a month ago and check them every once in a while. I think I'll use the National Tank Sealer in my tank when I get it finished. It seems to set up harder, kinda like epoxy. The Redkote is a little softer, but the gas hasn't affected either one. I think they'd both be ok to use.
Just my opinion.
