    I use Steelgard on all my hunting firearms, trap guns and revolvers. A quick spray down the barrel followed by a brush or swab or a spray and wipe on the outside totally prevents rust. When the action on my trap gun is fouled by powder residue during heavy use, a shot of Steelgard cleans and lubricates it for continued use.

    Several years ago I used Steelgard, for the first time, on my flintlock after deer hunting on a snowy day. The gun was totally wet and fouled from being fired several times. The Steelgard spray quickly removed the black-powder residue in the barrel and on the pan and lock. I gave it a quick wipe and the next weekend when I wanted to go hunting again, there was no rust anywhere on the gun nor any slippery oil film or solvent smell. It was ready to load and use. Now I use Steelgard on my flintlocks after every use.

    My father-in-law introduced me to Steelgard. I keep a can on top of my gun safe so it is handy to use on my guns before storing. A spray into the action and down the barrel, and on the exterior, followed by a bore patch and quick wipe has proven to be an effective cleaning agent and great rust preventative, even when condensate formed after applying Steelgard on a cold gun.

    I have had a chance to try it out on quite a few guns and have to say it is wonderful! Some of the guns I recently used it on were really gunky and had minor surface rust. By applying it to the rust and gunk and letting it soak in for a while, most times I was able to remove these problems easily, some gunk took more than one application and soaking but it worked excellent for the really hard places where it is difficult to get a brush, swab or even a pipe cleaner in and made the actions work smooth as silk. After cleaning and using it instead of regular gun oil, it really brought out the sheen of the blued metal parts and made the colors of case harden really stand out and look absolutely beautiful. One customer had an old double barrel shotgun that I worked on for him and he said that he didn't remember the gun ever looking so good. I am very happy with Steelgard.

    Ordered 3 cans and they sent 6 as I was the first online customer…..works good inside for cleaning and light coat outside. It stays very wet on patches and breaks down build-up inside barrels quite fast especially if you let it sit for 5 minutes or so.
