Guys... There has always been cross talk on what finishes to use on firearms i.e.: DuraCoating, Rust Blue, Park, Cold Blue etc.. I've done a bit of restoration work and so far have been able to do all my work with DuraCoat or Cold Blue.. Now I believe it's time to get into the prof. finishing processes and setup for hot bluing. I want the bare bones of what I'll need specific to getting a good hot blue job accomplished without slamming down 2k for a kit like brownells sells. I believe I could get away with a black iron tank for the bluing and another for the water bath, a burner, thermometer, and propane tank. I already have the safety gear (respirator etc..) Anyone experienced in this process can set me up, I'd appreciate it.
