I'm restoring a Gottlieb Abra Ca Dabra and dismantled the upper apron and arch (which creates the top orbit for the ball) and while cleaning the arch, I noticed what seemed to be some of the silver paint peeling. When I ran my finger around the arch, traveling area the ball would contact, I could feel that the surface was rough where the paint had peeled. My concern is that this rough surface will end up scuffing the ball.
Any suggestions on what to do with the arch? Should I try to strip all the paint and then polish the metal? Or repaint it? I'd like to make that surface as smooth as possible.
NOTE: The photos make the arch look bronze, but it is actually silver.
