## Description

Birchwood Casey Perma Blue Paste/Liquid - Birchwood Casey offers you the best ways to touch up scratches and worn spots or even completely reblue most guns. It will give a non-streaky, even blue-black finish to steel (except stainless). Both Perma Blue Liquid Gun Blue and Paste Gun Blue provide great bluing to metal that has already been thoroughly cleaned and is free of rust. Perma Blue Paste Gun Blue is slower to darken than Liquid Gun Blue, but will build up a denser finish. The best way to touch up scratches and worn spots on a blued barrel. BIRCHWOOD CASEY Since 1948, serious shooters, avid collectors and professional gunsmiths have relied on Birchwood Casey for shooting and gun care products; Birchwood Casey has pioneered innovative products with an unwavering dedication to quality.

Review: Works and looks great!!!!!!! - 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.
Review: Super easy to use! Do not need that much either!! - 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!
