After hearing all the time, pain, and cost that Dan Heath went through to build his aluminum tanks, I'm still using vinylester, foam, and fiberglass. I built an 8 gallon wing tank in one day (way less than eight hours of actual work) a few summers ago, and it's never leaked a drop. Vinylester is impervious to ethanol and autofuel, and I've never had a problem with it, despite running at least 5000 gallons of it through my tank. There is something to be said for aluminum...generally if it doesn't leak in the beginning, it likely never will, and you don't have to worry about what kind of fuel you're putting in it, but you may discover issues with the sloshing compound later on. But I'm sold on the speed and simplicity of the glass tanks. There are links to the tanks I've built so far at http://www.n56ml.com/kft.html http://www.n56ml.com/kft.html and http://www.n56ml.com/900hour/ The last one shows how you make a "ledge" to set the top on as a last step. Once you have ledges all the way around the top, put a generous bead of flox on it, all the way around, and then press the top in place and weight is down at the ledges to insure a good seal.
