Don, I don't know if I have the answer. I just rebuilt my Zenth 2 carburetor, and searched for a gas resistant paint. I did paint the carburetor, so I hope the paint will hold and be resistant to gas. The paint is RUST-OLEUM Engine Enamael. The paint claims to resist heat up to 500 degrees F, AND claims to be "gas and oil resistant". I guess time will tell. The sheen on the paint cap is a dull black, however, it actually turned out to be on the glossy side. I have been told that the paint needs to be on the glossy side to be gas resistant. The number on the spray paint can is 248936, and states to be "semi gloss black".
