Any shop that does chrome plating can do it. My 20 pound pile cost $100. Clear (white) zinc is the original finish all nuts and bolts (plus misc hardware like carb bowl clips, choke lever, rear brake stay, axle spacer, peg hardware, wheel spokes, etc) come with; the yellow zinc is what CB750 spoke nipples, stand springs and 4 battery tray washers have. Not to be confused w/ chrome plating, which some hardware on CB750 uses (handlebar clamp bolts and washers, clutch cover screws, rear axle nut, etc). Should last many, many years.
