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

Dang, this stuff works so fast you better not blink!! The beauty ring bolts in my bronco were kind of messed up from removing a couple times so bare metal was showing through the black.I poured some of this stuff on a bowl, dropped the button head torx bolts in and Shazam! No more silver was showing. Incredible. They look fantastic.One difference from the stock bolts is these come out with a matte black finish while the OEM Ford bolts have a shine on the black. I waxed these baby’s up and they look very, very close to the stock ones. Nobody would ever know.I got so punch happy I took my eyeglasses apart and threw the frames in but no go, this stuff only works in steel not aluminum.Oh well, can’t win ‘em all.This stuff works really well, if you need to blacken some steel hardware…get you some!

Followed the directions-wire wheel or sand blasted, de-grease and it worked great. Tried wire wheel and sand blasting, both looked good to me. Soaked in WD-40 or equivalent overnight

I used this to darken a cold blue finish....that turned out actually bright blue. Got it to more of a really dark gray color. SO, for my purpose this did ok. It goes on very "Splotchy" but smooths out over multiple applications if you APPLY it lightly with 000 steel wool as the only applicator.

Great stiff to protect bare metal. I dillyte it and put in a spray bottle for large areas like my workbench. Wear gloves, dont breath the fumes, rinse well with water after alllication.

Worked great for re-bluing this Coleman black band. Prepping properly is critical for good results. Strip to bare steel, wipe with alcohol pad and brush on, rinse with water and blow dry with compressed air

Works like advertised

easy to apply but does not work properly and does not protect against oxidation

Last forever
