I don't think I would want to coat the inside of a gun bore with anything,that can't be removed. Sounds like the Moly craze that hit years ago. It was the greatest thing since sliced bread,UNTIL shooters discovered that their bores were rusted under the moly coating. Seems that moly is hydroscopic(draws moisture like a sponge) and the barrel that were treated with it and used in high humidity climates were rusting under the coating. I'm not saying that will happen with this stuff,I don't know anything about it! If I shoot T7 hunting,I just take along some patches damp with Mean Green window cleaner in a scoal can,and use it instead of a spit patch. I have never been able to get a second shot off at a deer I missed,so speed in reloading has never been an issue. Ron
