    I have 4 sets of 914 wheel bolts that need restoring; copper plate then cadmium plating. So I need to find a plater.

    Very interesting for RR owners....but cadmium disappeared from the German fastener industry, and Porsche, sometime in the late 50s-very early 60s. The only exception on late 356s and 900 cars were the seat rails which were supplied by Recaro who must have accumulated a huge warehouse full of cadmium plated rails. The rail construction changed in '74, but cadmium was used up through the '73 rails. The Cadmium urban myth monster will not die....all that yellow stuff is clear/silver zinc with a yellow phosphorus/iridite wash.

    I did have a set of ATE cast iron calipers which would not take yellow zinc and we had to plate them with yellow cadmium....can't remember which car/model, but only that one set.......my plater said something with the iron alloy used by ATE. All other iron calipers were yellow zinc, again.
