My experience with Krylon has not been nearly as good as with Rustoleum.
Krylon does not spray as well, and doesn't have as much gloss. I'd say that it is barely adequate for gas models, but if you want to use it, go ahead.
A similar product would be Ace brand aerosols They spray better than Krylon and possess a higher gloss. I like Rustoleum better, but I use a fair share of Ace aerosol paints.
