If you don't mind fussing with enamels, check Xtracolor. It's made for Hannant's by Humbrol, but to me it seems to have a more finely ground pigment. It goes on like butter, covers well, and levels nicely. They have various national military aircraft colors, both WWII and modern, including AN colors, FS, etc. Most are available as gloss, making decal application easier. The paints come in Humbrol style cans, and though they're a bit messy, they seal well and the paints have a long shelf life, even after they've been opened.
