    Is there a good cold blue that will do a good job on a trigger and trigger guard. Tried 44-40 and after blueing could wipe the blueing off with a rag.

    All cold blue will rub off. Cold blue is only good for things that are never handled. Where hot blue won't stand up cold blue does not have a chance. waste of time and money.

    And after all these years I thought that "Cold Blue" was the after effects of a frigid date??

    Cold blue does not just rub off. You must follow the 6 P principle if you want good results.

    Proper preparation prevents piss poor performance. HMB

    hmb, you are right, it doesn't just rub off, it wears off, very quickly and turns into a transparent gray. . It is an exercise in futility regardless of preparation. The way I do it is to bead blast the part then heat it in the oven to 300 degrees. Apply the cold blue until the part cools then card it with oil. Looks great if it's just for lookin at. I have had best results with Brownell's Oxpho blue. 44-40 will rust for days afterward, so it has to be rubbed with oil daily for a while. If cold blue worked no one would bother with hot blue.

    Try applying the cold blue with a pad of 0000 steel wool. Rubbing gently while you apply it. Doing that removes any oxidation and lets the chemical reaction proceed at an optimum rate. HMB
