When I was working at Chrysler, I did a project for accessory chrome step bumpers. It involved discussions with the manager of the Chrysler plating lab, a long time employee.
In an off conversation he recounted that when he started in the chrome business (before any pollution controls) it was easy to spot a guy who worked in a plating shop - the fumes would eat holes through his nose after a few years!
Love the look, but chrome plating is nasty.
