My friend and I saw your display at the Valparaiso Gun Show. I was skeptical of course, but my friend bought a bottle for himself. When we got back to my house he told me to keep the bottle and try it on my AR 15. The salesman had said how good it would clean up a carboned up bolt. It sat on my work bench for a week or two before I got around to re-cleaning my AR. I could not believe how well it worked! So, in the interest of a true product test I cleaned a few more of my guns. It truly makes cleaning guns much less of a task, and no stinky chemicals to boot. I ended up buying another bottle at the Indy show to give to my friend, I would have felt bad about giving him a half empty bottle. Thanks for a Great Product.
