Following along with interest.

Yes there is a chance. It is possible that Glyptal is the only good solution. I Googled this quite a bit and a few things are in my favor. Glyptal is used in engine blocks that get hot. My mill head won't get hot. I found people that successfully used Rustoleum to spray the inside of gearboxes so I know oil based paint can be successful. Last, the Chinese company that built my mill did a half hearted interior paint job which I know wasn't Glyptal and it held up fine. I mentioned Glyptal because that is the proper way to paint a gearbox. I do not suggest following what I did. You are right I may regret trying to save $35.
I'll report back later on how it goes. Hopefully I won't see bits of yellow paint floating past my sight glass. If you want to paint your head interior and be sure it's right, use the Glyptal.
