    i just redone a nef r92, and the gun turned out good but the cylinder has small reddish brown area's here and there and in the notches. also reddish brown places in the cylder holes, i oiled as soon as finished so i don't know what it is. it doesn't look like rust as its in small tiny streaks here and there. is this rust or what?, i can't post pics as my camera is tore up right now. i used birchwood casey perma blue. thanks

    i kept rinsing with water and bluing, and its better but i still have a problem. the cylinder notches have brown color to it and the chambers do too. the rest of the cylinder looks fine, don't have any idea what i did wrong.

    When you blue a gun it must be clean and must not be touched with bare hands or get any thing on it. This said if it is touched or contaminated prior or during bluing you can get spots. This may not be what it is but I have seen this happen more than once. Unfortunately the cure is usually a redo. Try cleaning first, you can even try 0000 steel wool and a fine oil. If that does nothing its in or under the finish.

    i am thinking of engine block paint, will i have to remove the bluing to put it on or can i just clean the gun good and spray it on? thanks

    Is it the ceramic paint? I've used it on mags and it holds up pretty well. As long as the gun is cleaned and degreased the blue shouldn't affect it.

    Update!!!!!!!!!!!!!!

    i went and got some dupli-color engine enamel with ceramic, i painted the whole gun. i have been trying to remove all the oil on it these last few days, seems it just keeps creeping out. it may not turn out as well as i hoped with the oil coming through the pins and around the hammer. hopefully most of it will stay on and i'll have a finish on my gun. thanks

    the gun barrel and frame did fine with the dupli-color paint but the cylinder the paint came off after fireing. i cleaned it real good and blued the cylinder again. then again and cleaned and blued again. i even heated the metal before i blued, after i finished i left a good amount of oil all over the cylinder. i did this yesterday and i went into the room just a few minutes ago and where i blued the cylinder its got a brownish color on it. it almost looks like dull brass color, there is some blue there but mostley a ole brown color. so i don't have much more money to put in this, so will this hurt anything if i keep it oiled? its going to be a woods gun but i don't want the rust to hurt the gun any. should i try something else?, as i'm out of blueing. or will it be ok and not get worse if i keep it oiled? thanks

    I have had good luck with Dura-Bake. It will stink up the house, and is best done while the wife is out for the day, but it sticks well, and looks decent.
