How to fix pitted chrome interior pieces

If the pits aren't too deep and the material is thick enough you can sand and polish the pot metal. A customer of mine did that to a pair of tailights for his 57 Cameo. They looked like chrome but still had small pits that couldn't be sanded out. The professional refinishers drill each pit out and fill with ?( whatever) sand and replate after a few dips of copper to cover the impurities. Very very expensive I might add.
