    Hey guys. Seems like this is the most popular topic but I'm building a UDS with a used unlined barrel. Used a propane torch on the outside. While burning the outside, the inside changed colors and now has a blueish tint. Safe to use or do I need to scrub? You can see where I scrubbed a section off. thanks!

    Yes, just wipe it all down with low odor mineral spirits and getter built... getter done!

    Totally safe to use as-is.

    In fact, I kind of like that fire blued color.

    Great! Thanks! Assembly is done and am waiting for the paint to dry.

    Is that blueish tint considered rust inhibitor?

    It is a thin oxide layer that will inhibit rust, but it is very fragile. Oiling it helps, but in this case it should be seasoned anyway.

    Sorry, I misread the original question. I thought the barrel in question was a new unlined barrel
