Green chromating
+++
How to get green chromating in passivation of zinc electroplated
on steel, and what about the chemical composition and the process ?
It's a part of my research on electroplating on different metals, in
this case, it's about protecting steel.

The good stuff is very proprietary, IE: you have to buy it from a
reputable company. You may find a few very old references in the old
trade magazines. Many companies no longer patent their products as it
provides a fast track for others to reverse engineer it. They just
keep it a secret and the rip offs also keep it a secret.
