JAX Black Darkener - Recommended for Iron/Steel Parts

I love it. I used it on my Woodsrunner rifle. I did my lock, as well as all the brass, and screws. I’m also did my barrel. I’m on my second or third bottle.

Amazing finish

An amazing product. I polished the SMR trigger guard to 800 grit wet/dry sandpaper, degreased with mineral spirits (any degreasing agent will work). Six light coats of Jax (more for a darker finish, less for a lighter one) applied with a gray Scotch Brite pad. I rubbed each coat very gently. I stabilized between coats with a 50/50 solution of baking soda and water. I didn’t let the piece develop any rust but rust can easily removed with a piece of denim or gray Scotch Brite. Finally, heat the piece to 350 degrees in motor oil for 15 minutes*, let it cool under tap water, polish and apply gun oil.

After the initial filing, sanding, and polishing the entire process took about 1abd a half hours.

*Your partner probably won’t appreciate the fragrance of of smoldering motor oil so heating the piece with a torch is probably a better idea.

Great product and easy to use. Make sure to wash your parts well with soap and hot water to remove all oil and grease. My metal parts came out fantastic!

Jax black worked great. Was able to get the color I wanted to a “French gray” on my Woodsrunner barrel and lock.

Great product.
Very easy to work with.
Great results.

I used it to make a patina on my woodsrunner barrel and screws. It worked well. I only did one treatment and worked it over with some red scotchbrite pads. I had thought of leaving the barrel in the white and letting it develop patina over time, this started the whole process well.

I was trying for an aged gunmetal grey finish on my recent SMR build. The JAX Black worked exactly as desired.

Worked amazingly on the metal parts on my SMR and also worked great on darkening down a brass guard and pomel on a Bowie knife I made.

Great product! Works perfectly!

I used this product to finish all the steel on my recent Fowler project. The finish turned out perfectly. The black is so dark that it has a blue shine to it.

I used JAX Black on the barrel of my Southern Mountain Rifle.
at first I thought it was going to be too dark, or at least much darker than I wanted. but I followed the directions, rinsed and took a scotch pad to the barrel to "weather" the finish. it's turned out amazing!!
I followed up with applying some of that yellow barrel butter and a fine steel wool.

Was very easy to use with great results use the little four 0000 steel wool buff back and got the results I was looking for would highly recommend this product

The stuff was excellent darkened up the barrel trigger plate trigger scuffed back with a gray scotch pad came out the color I wanted .

Best looking and easiest finish I've used. Worth every penny.

I've used JAX Black on both my Southern Mountain and Woodsrunner rifles. This included the barrels, locks and other metal parts. I found it gave both rifles a realistic vintage look that I really appreciate.

I used this product to darken the background on the engraving on my side plate and on some iron screw heads and it worked really well,where I wanted it darker I gave it more than 1 coat

I got a bottle of JAX black to try out while building my Hawken kit. My original plan was to brown the Hawken until I knocked over the browning solution… my concrete floor in the garage is now brown, go figure. So I than used JAX over the partially browned parts and wow what an interesting finish it produced.

Very good product. Works well and easy to use. I use Iron parts on simple / plain Tenn or mountian style rifles. This give the steel parts a good traditional look on this style of rifle.

Very easy to use and nice results on the first try...keep it wet to even put...happy with the results.

Easy to use and great results.
