Yes ZBC on steel or hard anodize black if they’re the aluminum fasteners. You need something wear and UV resistant and both meet those requirements.

Neither are cheap processes on the consumer end for small quantity.

You can do a home brewed “anodizing” on steel parts with and acid etch color dye process by taking sulfuric acid and ultra concentrate color dye(fabric dye) and dipping the parts for a brief time. Just be UBER careful using that stuff. Or you can try PPG Rust Mort. Soak parts ~24-36hrs and they tend to get a grayish/black corrosion barrier on them

Interesting. Where can I pickup sulfuric acid other than stealing it from the lab?

where can i find the ppg rust mort? would it chip off?
