I have some parts that require some cold blue treatment.
anyone got any idea where I can find something for that? Ive searched trademe and google for Jax iron steel and nickel blackener, and for "cold blue" products on the usual sites, TM, topmaq, machinery house, but nobody seems to carry anything.
make sure you degrease the bits thoroughly and do not touch them with your hands anytime during the procedure.
