Birchwood Presto Black STEEL PC9 - versatile blackening solution for iron and steel alloys traditional patina blue and black oxide touch-up (8 oz)

Works great

tarnishes steel beautifully. very happy with how it turned out. I sealed it with satin lacquer and my sculpture looks incredible. super easy to use and kinda hard to mess up

This stuff works excellent! Used it for a bunch of raw steel that I welded up for under-counter brackets, vintage ceiling lighting, etc... Was able to make it look super rustic, without the need to simply paint it black. Depending on how much you use, or how long you leave it on, will determine how dark/blackened the metal becomes.

I needed to sand down the grip safety on a parkerized 1911 A1 a bit as it dug into the web of my hand. Used the Presto Black Steel when I was done and it came out great. A little darker than the original, but you wouldn't really notice unless you were looking for it. Holding up well.

Doesn’t work as expected. Eats the metal in some areas while not changing other areas. I’ve tried many cleaning and prep methods and can’t seem to get it to work good.

Not perfect but does a very nice job without a lot of hassle m

Works great, works quick, just be sure to clean the surface really well. Any grease or oil with stop the reaction. I used isopropyl alcohol to clean my surface.

I use it to blacken silver screw heads on a few projects. It does not provide a perfect finish as you might get with anodized black screws but for most of my needs it is more than satisfactory
