Removing caps on '37 hubcaps?

[hotcoupe]

I concur with what jimTN said , don't apply a lot of paint to the portion of the hubcap where the stainless steel cap goes on. I have used Variprime, made by Du Pont. Place the carbon steel in the freezer overnight and heat the stainless in the oven @ 200° for 20 minutes, it will slip right on.
Hope this helps,
Tom
