I do not have first hand experience, but based on some reports by buddies still "down range" it does work as advertised. I have done the heat and cure on my M4gery as well as some hand guns, my EDC G19 included. I found in the process of doing the cure, guns I believed to be clean, got even cleaner.
I did my LCP that is always in my pocket since I had been having some rusting issues on the blued slide. so far no rust since the treatment. If I can run my AR somewhat dry and it makes cleaning quick and easy, I am sold.
It would also be nice to just have one product to use and have it be not so caustic.
