[Roadsters] Bumper

[Gary and Cindy Ault]

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.
