IMO paint is like jewelry, you get what you,pay for. In order to be fuel proof the paint has to be catalized. Even the auto clear over latex is not going to be 100% fuel proof. Sooner or later fuel is going to creep in between the paint and the clear around edges.

That being said it all depends on how much you value your airplane. As for Bob and many more of us we don't mind spending the extra cash knowing that our airplane that we plan to have for years will look great and stand the test of time. For those on a budget, check into the Spray Max line of products. The cans are about 20.00 each so not really much more expensive then Lusterkote. Available is base/clear, single stage and primer. All fuel proof except the base. The base is very fuel resistant after being cleared.
