Hi All


On the rusty nickel issue I worked for a few months in a plating shop in the
70's during my engineering apprenticeship, there they would degrease the part,
copper flash, a few 10ths I think, then nickel plate and finally chrome plate
prior to polishing the nickel, the copper is there to aid adhesion of the nickel
to certain materials, all a bit vague now though due to the time passed.


Hope this helps.
