Wendell, During the construction of my turtleback and fuel tank I used a combination of West Systems for some parts and Aeropoxy for others. If it is any consolation the West Systems seems to be holding up better than the Aeropoxy so far. This fuel tank has had auto fuel in it for over 5 years. It is just recently, since the use of ethanol that I have noticed the changes in its integrity. Be sure that any sealer that you use is rated for auto fuel with alcohol. The Pro-seal that all the RV guys are using on their aluminum tanks will not even hold up to auto fuel with ethanol. Personally I don't like the idea of a sealer because if/when it starts to deteriorate and gets ingested into the system it will cause the same problem that I am having right now but maybe even worse.

Hey James, I have heard of fuel tanks becoming soft and leaking but not disintegrating. I was building my Cozy strake tank area with West Systems epoxy as many boat builders use this including to fuel tanks. E-mailed West Systems asking if their epoxy would hold up to alcohol in fuel and they not only answered but called me personally to say that it is not rated for alcohol. They recommended a Proset system. I then had to coat my tanks with that epoxy, hope they are right.
