That looks exactly like the corroded copper layer. The finished cad look should be a dull silver finish. I have about 3 sets that I want to have refinished. Cad plating is getting difficult to find.
Your right, it does look like copper oxidation in that pic, but if you have them in hand, you can see that the dark green stuff is definitely paint from when they dobbed on for the recall. There are even brush marks in the one on the left. When I first got the car 35 years ago, it was more obvious as the bolts still had their finish and the blobs of green paint on the centers. I think the lighter colored green in these pics may be oxidized copper though. It isn't paint anyway and does look like green copper.
I'm sending all my stuff to
Quality Plating in Salt Lake City. Eric Shea recommended them to me. They still offer cadmium plating. If that is too expensive, I'll probably go the bright zinc route like
@Cal showed. Those look nice without too much bling. BTW, great wheel in general Cal. I see a lot of these with the petals and rims over polished for my taste. Yours look perfect. What's your secret?
