Birchwood Casey Perma Blue Liquid Air Gun Shotgun Blueing 90ml [13125] Blue Rifle

I used this Perma Blue paste to coat a vintage York Barbell. I used hardly any of the tube to cover about 4 feet of 1-1/16" bar with 4 or 5 coats. Key points to remember, first, get the base metal clean and scuffed uniformly! Any dark spots, discolorations, or deep sand scratches will stand out. Secondly, HEAT THE METAL! It's actually better if your surface is NOT hot, just warmed up slightly (let's say 110-120 degrees, warm to the touch). You could even leave your part in the sun for a few minutes to warm up. Get it too hot and the paste will dry quickly, be uneven, and come off in chunks (rather than allow you to spread it easily over the surface). Similar to you trying wax your car on 110 degree day in the direct sun. No good! FYI, I used acetone to clean the barbell before applying the first coat (and in between coats). First coat goes on a little uneven and blotchy. I let it setup for a minute or so, then rinsed the part off with water and a clean towel. You'll want to lightly scuff the part with a scotchbrite pad between coats (maroon worked good for me), after rinsing the previous coat off. I used a propane torch to heat my base metal back up to slightly warm (move quickly!!), then wiped it off with acetone/clean rag seconds before applying the next coat. Open flame may not be the best idea, but it worked flawless for my situation....just don't light your acetone rag on fire! Heat gun would be better for coating an actual firearm. Repeat the above process until you're happy with the color. The finished product will be evenly coated. You need to rinse it (obviously don't scuff it after the final coat!). End result is nice and smooth, not sticky, and not thick. Color is brown/bronze with this product when applied over bare (scuffed) steel.

As you can see I used this on a blade. I'm also going to use it on a barrel eventually. It's quite easy to use. Just degrease whatever you are blueing, clean it well, dry it off, then apply some of the goop and rub it in. I did a couple coats and when I was done I waited a couple days then went and used some whetstone powdered cloth and rubbed it down a lot after cleaning it again. The hamon is visible still too and it looks pretty cool. Then I applied some oil and all is well. I'm happy to have this as I will likely scuff up the blade during cutting practice, so after I re sharpen and polish the blade I can blue it again fast in the future. This will work on any steel I think. Super awesome stuff. You won't regret it!

Great bluing compound. Works quickly and produces a very nice patina with minimal effort.

Well packaged and fast shipping.

Works great for touching up guns, or doing the entire gun. The paste allows more time without a mess

Fast bluing, easily controlled paste bluing for ferrous metals, like iron and steel. Easily controlled and stop the chemical process. Wipe it off and oil it to stop. Rub on more to make it darker.

I never guessed bluing metal would be so easy. I spent the $10. I rubbed it on what had become bare metal and it instantly darkened. I didn’t realize an application would be only 30 to 60 seconds. You can wipe it off and repeat until you get as dark a color as you want. Then wipe on a drop of oil and you may have erased decades of what looked like wear but was only the loss of a nano layer of oxidation

I used this to touch up a few parts on an SKS I built from spares (yes, I actually built an SKS. Yes, I was very bored.). While it seems to make a nice, dark blue it's easily rubbed off and will mostly come off with water. I f put about three coats on and then give it a nice wipe with an oily rag. Seems to work ok and gets rid of the weird smell. Oh yeah, this stuff smells kinda weird. Don't know what the deal is there. Most likely the reaction of the chemical with the steel. Anyway, if you need touch up on a cheapo gun then go ahead. If it's a nice piece you might be better off using another kit or just leaving as is. I'm happy with the results when used on my $65 home made FrankenSKS.

Only complaint if I had to come up with one is that the package was leaking when I got it but other then that it work’s really well.

Excelente producto muy recomendable para pavor materiales de acero

Very impressive. Used for touch up, didn't seem to mess with the areas that already have bluing, only the ones with bare metal. Covered scratches no problem. Wish there was a more accurate tip for the tube but you could fill a needle if needed

Fácil de aplicar y no se cupa gran cantidad a mi parecer

No funciona, ya casi voy por la mitad del producto y no cambia ni un poquito el color del metal.
