Lacquer over enamel is a no no, yes? And I'm assuming this is true with butyrate over enamel. If the colors I want to use I can only find in enamel but I want the fuel proofing of the butyrate could I use shellac (Rustoleum"s Zinsser Sealcoat) as a barrier? I'd rather not do the test if someone knows the answer.
Thanks,
