A #1 bestseller, PERMA BLUE Liquid Gun Blue is the proven way to touch-up scratches and worn spots or to completely re-blue most guns. It will give a non-streaky, even blue-black finish to steel (except stainless). All parts to be blued must be rust-free and thoroughly cleaned with a metal cleaner such as BIRCHWOOD CASEY's Cleaner-Degreaser before applying the blue.

Rated 3 out of 5 by Works fine on newer firearms.. See my other review on the paste blueing..."Tried to touch up my 1920 P08 Luger and on one small section I applied the gun blue it took the bluing off the Luger. Was not a happy camper...The pistol is now at the gunsmith and needs to be re-blued. The gun smith rubbed the area with a soft cloth and attempted to touch it up to no avail. More blueing came off and it just made it worst. I now need to have the pistol totally re-blued!" October 14, 2013
Rated 5 out of 5 by Good product Had to do a few rusted spots. Used steel wool to polish up and then applied the gun blue. Touched up nice. It doesn't match my gun exactly (its a different process of blueing so I wouldn't expect it to) but it does blue it and made it look much less noticeable, and more importantly my shotgun in now protected. For 10 bucks I say you cant beat it. September 15, 2013
