Birchwood Casey Super Blue Liquid Gun Gun Blue 3 oz

I have a .22 rifle that was made sometime around 1918 or so, that I got from my grand father. The outside of the barrel was rusting. I cleaned the rust off and used super blue to re-blue is and worked great. Hasn't worn off yet and I carry that rifle in my truck a lot. I cannot say that super blue works any better than any other gun blue, but it did a great job for me. I recommend this for any looking to re-blue a gun.
