Check on Martin Senour, Napa sells it, if you have Napa, look through there book, they have acrylic enamel single stage paints in the front usally, that are not production car colors, there are a lot of yellows. Don't take this offensive as I'm seriouse, but JD yellow is 6 bucks a quart and is almost like a daytona yellow when you buy the rustolum brand as there colors are not perfect match to JD colors, I have a quart of JD green and it is more of a hunter green than the true JD green. The Martin senour purple I'm getting is single stage acrylic enamel and is 125 a gallon.
