You might want to take a look at Tamiya AS-12 (from the aircraft spray range).
Its a nice fine silver that goes on really smoothly and covers very easily, it dries to a satin finish so you will need a clear coat (TS-13) but I find it works so much nicer than TS-17 Gloss Aluminium.
I also use this stuff as a sealer sometimes over filler and when needing to stop red pigment bleed .... like when painting Ebbro's Lotus 72C white.

Edit... Here's the AS-12 used on a Toyota 86, showing how fine and even it is. In this application I used it to seal some filler and as a base for the Metallic Orange topcoat, but it could just as easily be cleared and used as the finished colour..
