-----Rust to Gunmetal
2004
I am a conservator at an art restoration company. I have a table that has a kind of gunmetal (gray-blue-black) look. The table has rust in the center of it. There is a finish look to it, I have tried

⇦ on
eBay or
Amazon [affil link]
and
Jax Patina
[affil link] metal finishing solution to change the color with out using heat. I am concerned that if I did use heat it would change the look of the rest of the table. The work I am doing is helping, but it is not a real match. I would like to chemically change the rust areas and not have to use paint to get the color. What should I be using, I am setting here with the Fisher scientific catalog and I need direction.
Thank you all for you time.

It's very hard to match something like that without a lot of trial and error, but it sounds like the finish may be gun bluing. This will have different looks depending on the smoothness of the underlying finish, so the rusted area may need to be buffed before bluing.
