Grill a couple of posts up. If your chrome is in decent shape, the part that is wearing off is a silver argent paint. This guy seems to have most of the recipes for the different Mopar trim and interior paints. Nice guy to talk to. Will put it in a rattle can for you or by the pint. Around $20 if I remember correctly. Silver argent wheel paint may get you close as well. Website and phone number the same. I believe he uses PPG paint but puts it in a generic can.
