For all Cadmium, Zinc, or Phosphate plating, hardware and parts are cleaned and chemically stripped of all original plating. Pieces are inspected for flaws which are repaired when possible. They are then tumbled, specially processed for desired sheen against plating type, all bolt threads are wired brushed by hand and only then parts are hand-wired and plated. The end result is the best quality plating possible with period-correct color.
