    01066046-900E-4AA9-AFA8-B9520A7FA909.jpeg View attachment 248039 so I have been tinkering with some cheap cold blue until get sand blast materials figured out. I bought some cheap super blue and attempted a few diff ways of applying until I found what seemed to work best. I like how it turned out. Just not sure how long it will last an stay nice. Also was curious if it’s a the more I put on the longer will hold up or? Below is a pic with 3 coats anyone utilized this coating for a period of time?

    Don't know the answer, but may I ask what cold blue you used?

    Cold bluing is just a chemical reaction in the metal it doesnt get thicker the more you put on like a cerakote or gunkote finish. It may get darker the more you put on because of the metals reaction to the chemical.

    I also figured out fairly quickly that any type of application that involved rubbing on will look bad and uneven unless you buy enough to be able to immerse the part the best way to apply I found was to spray it with a air brush

    I can't speak to how well cold blue lasts when used as a stand alone finish, but I use it to touch up my carry guns and it seems to last pretty well.

    Be careful with that finish, I remember reading that it does not offer any anti-rust properties like the standard blueing process.

    Over the years i think I've used ever cold blue on the market. All of them are made of the same basic formula just differing amounts. Brownells sell quite a few versions and oxpho blue is the most popular. I actually use dicropan IM from them. It is actually a replacement for rust bluing.. takes a bit of work to perfect the process, but it is seems to last longer than any other cold blue and does not change color over time. Brownells has specific instructions for each. Pays to read them

    It can be durable if you clean the surface with alcohol and use some heat. I prefer the paste/gel type products...they seem to work best for me.

    I have been using the Kleenbore Black Magic and it seems to be darker than the Birchwood Casey Presto Mag, but your finish came out great. Too bad I don't airbrush...

    Looks great. I think it will be fine. Just keep a silicone rag or oil and it should be fine.

    Although the instructions say you can leave oil on the surface, I think Brownell’s Oxpho Blue works best if you degrease the part and heat it up before application.
