I have a nickel era 1928 Packard that I am restoring. I know the judging rules indicate that plating should be "as manufactured". I have many small interior parts that have to be plated. Chrome resists tarnishing much better than nickel and I would like to know what kind of penalty I would incur for having small items chromed rather than nickeled. Also the kind of nickel plating called hard nickel is brighter but not chrome. Is it allowed? Large items such as headlights, radiator shells etc would be nickeled, but I am just interested in chroming small items.
