Really like the DARK red used on the flywheels, as it has an oldish "feel" to it!
The mounted wheel is original paint. So, I had an original color sample. Jut some trial and error with the colors I had here. Oddly enough, Harley Davidson Deep Candy Red with a touch of brown and a small amount of thinner shot the closest color. I didn't prime, as they didn't seem to do it from what I can tell. Just fill up the airbrush and ran about 10 light coats, then clear lacquer.
The toughest part is getting the color right but hey you can always clean and respray if you mess it up.
