Hi all, I just wanted to drop this out there since I havent really found any definitive answer during my searches.
I have finally found what promises to be a fuel immune resin, including ones with a high ethanol content if I am to believe the business owner and at this point I have no reason not to as he comes well recommended.
I should add that I am not affiliated with company and am not endorsing the product as I am just now starting to work with it. Time will tell if it is as good as claimed.
I picked it up from expresscomposites.com, PN AOC764 and the price was dirt cheap at $68.52 shipped which was both 1 gallon of resin and 4oz of MEKP.
I am going to make my first gas tank with it during the coming weeks and will keep you updated but according to the owner (nice guy, I spoke with him on the phone) he has had products soaking in ethanol rich fuel for 6 months now without any sign of degradation.
