There is two products. Rustoleum Mirror Effect and Kylon Looking Glass. These are the cheapest options I have found. If you want to use your airbrush you can looking into Motochrome by Motostorm, I have used all three of these and give really good results. The one thing about them is you pretty much have to epoxy coat them if you dip them in KBS it will reactivate the finish and dull the chrome. I can post pictures if you like
