Yup, Rustoleum works great for model paint. I have done several sport models with it. Like Bill said, use the enamel in the spray cans. Stick to the solid colors. Use as little as possible because it's kinda heavy paint (the stuff covers pretty good with light coats anyway) and let it cure for as long as possible before getting fuel on it. Using it over open bays is fine, but as stated a repair would be more difficult as dope eats all other paints. I usually MonoKote the open bays and spray the solid ones. If you let Rustoleum cure well it can be sanded and polished too. It's by far and away the best out of the can quickie finishing way to go.
