I have used Future, gloss enamel and gloss lacquer. I find that I prefer the spray can(lacquer) over Future and enamel. You only need one pass, with the spray can. With Future, you have to build up layers. The same goes for enamel. Also, you don't have to strip your airbrush afterwards. The drawbacks are, lacquer requires 72 hours minimum to cure and it is advisable that you spray outside. You can handle the model, after a few hours no matter which medium you use. Just mho.
