Jaxx,
It's a 2 1/4" Dubro nylon spinner.
Prior to painting, I cover with minwax and go over the whole thing with fine grit sandpaper, like 2000 or so. After painting, I usually find a few rough spots that need a little more sanding. Then I respray as needed.
The primary color is Rustoleum 'Aluminum'.

The yellow, black, and white paints are also Rustoleum. The red on the wingtips and tail is brushed on Testors. The red around the base of the canopy is actually red electrical tape. Tail numbers are stenciled on spray paint. Squadron and unit numbers are printed on an inkjet printer, cut out with an Xacto, and then pasted on. Same for the bomb logos, kill markings, and roundels. After affixing with paste, I cover the inkjet printed 'decals' with another coat of Minwax to protect from moisture damage.
Yours looks great, too, Jes! Did you also use the Rustoleum Aluminum paint?
