Years ago I think I read somewhere that chrome is porous and so if used alone
on steel/iron it will rust eventually. Nickel plating IIRC, is not porous and
so can be used to protect steel/iron more successfully. The best thing IIRC
for parts of cars/motorcycles being restored was to nickel plate and then
chrome plate on top of that.
Anyway I could have remembered this completely wrongly so someone with more
knowledge than me would be able to clarify the thing
Personally I've never had anything chrome plated but if I did want to chrome
plate something I think I'd enquire with classic car/motorcycle restoration
people because they do it a lot. There is very likely a newsgroup for classic
vehicle restoration or something. Might be worth a try.
