My 1948 Continental coupe has pitted pot metal grille pieces, tail lights, tail light spears, everything. Has anyone had experience with chrome on pitted pot metal? Some shops say put on copper, sand and buff, re-copper, sand and buff some more until the pits are filled. I wonder about corrosion products left in the pits before the first layer of copper goes on and future bubbling. Some shops drill out pits to clean metal, fill with silver or lead solder, then copper, nickel, chrome. How about repair of broken pot metal? Any experience with Finishing Touch, Paul's Chrome, Ogden Chrome, R&D Finishing? Any other shops? Lots of questions, thanks in advance for help. Dan
