Cast Blast Finish

[Supergas990]

I'm working on painting the frame and components on my 1968 Corvette. In the past, I've used Duplicolor Cast Blast aerosol paint for springs and associated suspension parts.

Would like to get a single stage mixable for use in my spray gun, but can't get a solid match at Finishmaster and would prefer not to spend $15 per spray can to do this.

Anyone have a good brand and color recommendation?

Thanks - Blair
