  Jim,

"Rechroming" is a three-step process (after the original finish is 
stripped):

1.  A copper plating, to fill imperfections.   (May require multiple 
applications with buffing in between.)
2.  A nickel plating.
3.  The final chrome plating.

The copper is also probably needed to bond to the steel, an dthe nickel to 
bond to the copper.  But, I'm not a chemist so I don't know for sure.

So, if you send your bumper to a reputable chrome plater, you will get the 
pitting, etc., corrected as part of the process.  It is possible to 
re-chrome without doing a careful job of copper plating and buffing out 
imperfections, but the basic steps for correcting such imperfections is 
inherent in the process.

    Watch out for chromers that want to grind out the pits. Your parts will end up paper thin. You are better off with little dimples in the chrome rather than your bumper ground down to nothing. The key to getting chrome you like is to talk to the plater and make sure you both understand what is expected. If you throw your part on the counter, say chrome, and walk out the door there is no telling what you will end up with.
   
  Copper is very expensive, as is labor. If you want the pits filled with copper this involves plating and buffing several times. A lot of places won't do it and the ones that do charge appropriately, usually a lot. That's why they like to grind the pits out, fast and cheap.
