who does rechroming

If the housings are pitting, you are going to pay big bucks to get them restored as stated. The pits are picked with something similar to a dentist's pick to get it all out. From there they are plated with copper and polished down multiple times until the surface is even and flat. Then they are put through the normal plating process. Getting the pitting out is time and labor intensive, so let your wallet be your guide.
