The Jax product you will find most useful is the Jax Pewter Black. You should be able to achieve a dark grey to black patina on Zamak 5. A few experiments with application methods and dilution will be helpful.
I am looking to patina a material I believe to be zinc based, Zamak 5. Will any Jax products either darken it in a similar manner to cold blue on steel, or, alternately, make it iridescent and colorful?
