SPECIAL NOTE:
A lot of viewers have written to say that the MSDS lists nickel salts as carcinogenic, but I have not had a high degree on concern because I also see many other common items listed as similar carcinogenic risks. These include Diesel exhaust, gasoline, paint fumes, plastic glue, lighter fluid, lead and many others. So I believe with care, most of these can be handled safely. Please be cautious and respectful of any chemical. It’s not worth it to get hurt.
3 G’s: Goggles, gloves and good ventilation…
P.S. After many suggestions that I experiment with less expensive Nickel Sulfate, I’ve found a less expensive chemical combo that also makes a fantastic and shiny coat!

Thought I’d pass it on.
