Holley 94 rebuild

[3twinridges]

After a lot of trial and error finally got a chromate conversion coating on the carb bodies that I like. All of the small parts are plated and ready to go. Only part left is the base. What was the original finish of the throttle body? I thought about zinc plating the base and using a black chromate finish. Anyone tried that, my only other alternative is a matte black paint.
