What’s the best paint for steel rims?

Good Evening Moparians!

I copped a nice set of steel 1971 15x6 rims in town a couple days ago, and while the old chrome(?) plating looks good where it is, the rest of the steel would be better preserved and smoothed with a good paint job. This being so, I wonder if there are special paints for tire rims, or will the normal automotive paints suffice? Who among you Wise Elders has had to paint steel rims? I seek your lore and hope to apply some, then share my results.
