I was never able to get the phosphate finish as dark as the original finishes I've seen using these chemicals. A nice grey yes but not the crystalline near black finish I would like to duplicate, especially on the pulleys.

I get my chemicals from Lauer Waeponry.

You can use a ceramic hot plate &amp; pyrex bowls for small parts and bolts.
