Black Patina on Stainless Steel

[HPBotha]

Has anyone tried to do chemical patina on stainless steel? I am looking forward in trying this!!!

​

there is a link to a website available at the end, but i would like to know if there is a local variant available..... they sure do have a ton of options available to customize your metal finishes!!!

I have, it makes the steel super hard, Also its pretty hard to keep it consistent.
