More examples of zinc patina in this post.
1. Clean metal with wire brush to get off all zinc oxide.
2. Paint on a thin layer of Cupric Sulfate (while wearing gloves) Get Cupric Sulfate here at Rotometals
3. Wrap in thin layer of saran wrap so it does not evaporate
4. wait 3 hours.
5. brush off the high spots with wire brush.
6. Three coats of clear coat.
You can achieve much the same result with vinegar or HCl.
