Outlaw Simmons Gold
 
There is alot of room to move with metallics. Try a black undercoat for a rich colour. A silver or Gold undercoat can change the colour immensely.
 
Give the bottle a good stir before use, airbrush ready. About 15-18psi though a 0.3mm needle is a good starting point.
 
Outlaw paint is Australian made and owned.
