In all the years I've been messing with these trucks, I've never tried to separate the outer skin from from an original hub cap. I've got a pile of very solid 54-55 Chevy 3600 3800 hub caps that have no rust, but lots of repairable dents and dings. These caps will likely never be reproduced and so I think they should be repaired if possible. I'd love to tackle the chore myself. I'm just wondering if anyone has come up with a good method for separating the skins so that they'll go back together. My intention as of now is that these will be painted caps. I don't know if they could be ironed out to the degree necessary to plate them.
