In the very last picture above you can see how I airbrushed two Austral logos onto the yellow band in orange. This shows how much flexibility you have using computer generated masking film. I didn't like the orange, so I cut additional mask and carefully applied them over the orange logos. I then airbrushed a bit of white over the orange logos and shot silver (Metalume) over the mask.

I shot House of Kolor Metajuls over all of the colors to give it a metal flake look. They will pop when the clear is shot.
