When I purchased my 1931 42 convertible in 1984, the grille shutters neither worked, nor were they plated. When I did some elective plating, I removed the radiator and grille, replaced the shell with a better chromed one that I found somewhere, and plated the shutters. Moreover, I made the shutters functional. The improvement in appearance was astounding. When the shutters were closed, the effect was one mass of gleaming chrome. I definitely would wait for the plating to be done.
