I realize this is an old thread. But I haven't heard much about it recently.
My question is this: wouldn't firing a round and then wet patch then fire and so on, seal fouling ( copper ) in the barrel permanently?
That's not how the product was instructed to be installed/applied by the manufacturer. The bore was to be cleaned down to the bone prior to every treatment and additional shot fired. Forget all of that process anyhow. There's a newer installation process that is MUCH less tedious, and is now recommended by the manufacturer. I've used the new process on several of my rifle barrels and believe me, it's much less time consuming and seems to work just as well. If you want to send me your e-mail address via the LRH personal message system, I'll see if I can locate my electronic copy of the new Gun Juice application instructions.
The original instructions I received and used were so tedious, I don't know that many people would stick with it and do it properly. The new application instructions are the way to go.
Same to any other forum members. If you'd like the new application instructions, send me an e-mail address via the LRH personal message system. Reason for this is I don't know how to post an electronic document to a LRH Forum Thread. And I don't want to type the instructions, when I can send them directly via e-mail attachment.
I treated the exterior surface of several of my rifles at the same time I treated the bores using the new application instructions. Just got back from Kodiak Island. Spent 7 days in the off-and-on rain in a tent camp with no heat. I could tell that the Gun Juice treated barreled action (exterior) was helping prevent corrosion.
To the member that wanted hard evidence of improved bore/throat life, I'm not the guy to talk to, because I'll probably never shoot the throat out on any of my rifles. Other than maybe a 25 RUM. Cuz that cartridge may only take a couple hundred rounds to smoke the throat at 3850 fps MV. Point is, I don't shoot enough to shoot the throats out of my rifles.
A gun smith from Canada that introduced this Forum to the product claims he gets extended throat life. He and his customers may shoot enough to figure that one out.
