I have used truck bedliner on a couple of aluminum boats. No primer, just straight to the clean metal. It takes a beating pretty good. Metal prep is important. Rougher is better, and etch with acid. I like ExtremeLiner sold on ebay. Its a 2 part polyurethane. Comes with instructions and spray gun. For a tank I would use the finest rubber granules. I know you dont really need nonskid on a fuel tank, but the rubber is a big part of why this type of polyurethane is so tuff. And it looks good.
