Zenith carburetor black paint

[37 Coupe]

I have used the VHT "epoxy" on projects for the last ten years mainly for its ease of use and no primer required.It was very durable on items such as a set of new Stipe shocks a few years back. I did use it on Zenith Model B carb and the fuel was not ethanol but rec gas and it did not hold up on a pretty good dousing mistake ( choke /GAV on Model B open ),not good on fuel pump 1932. Paint was well cured time wise. Thanks for all the suggestions. I wonder what was used originally? It seems tough to remove with chemicals. I had a NOS Model B Zenith that I was just going to clean up and touch up that was shelf worn and looked dirty and rusty but ended up cleaning it with Gibbs oil and left it alone. I am just adding this,I think the fuel was ethanol that softened the VHT epoxy paint,it was already in the '32 Model B tank. I have not used ethanol and will not after an incident on my '37 Stromberg carb.
