Rasta, how did you prep the stuff before plating? Did you blast it yourself, or did you have that done as part of the service? My local plater doesn't like cleaning the stuff, but he gives me a great price if I bring the stuff in already blasted. It's a Royal PITA to do, but worth it.

Their minimum order was $45, and he told me to "fill a bucket" in addition to the spring plates so I could get maximum value out of the $45. Chemically stripping the parts was another $15.

The zinked stuff looks great! We have a similar service here. It is called 'yellow passivated'.
I was wondering how to preserve it: new parts lose their shine in a couple of years. Very thin (wipe) coat of oil or something?
I also thought of having all the CIS banjo bolts replated, but am still unsure if this will affect the fit or throughflow of these parts...

Are you sure that's zinc ? Looks like cadmium to me.

You can get zinc in yellow, silver. I think there is a third colour option too.
Cadmium is more corrosion resistant in salt atmospheres than zinc but it also looks like yellow zinc. But the real key is that cadmium is not selected for corrosion resistance so much as lubricity. i.e. it slides well. Ideal for mating parts that need to move over each other easily like spring plates on suspension components. You wouldn't want to use Cad on pulleys where you need surface grip though.

You can get:
Blue yellow green and black.
Green being the most corrosion resistant.
