Thanks for the comment.
You'll notice when you remove the grille (just six 8mm nuts) that there is a strip of plastic molding around it on 3 sides. It's attached with contact cement. I was able to peel it off carefully and save it. After the plating was done, I reglued the strip in place before remounting the grille to the hood.
Lexucan, The grille is plastic, Is there a specialty shop that did the plating ?
