Oh I will definitely have to peruse the paint aisle a little closer next trip....Hey Carl, Thats a wild li'l scoot!
I agree that Duplicolour is great stuff and most products/systems are compatible.
I've used their clear adhesion promoter under clear coats on bare metal and under their anodized finish over Spaceliner chrome with great results.
I often use and can recommend the (heavier duty???) wheel clear for bare metal and over paint as well.
(it's like just across the shopping center parking lot across the street from me)
Carl.
