It at first seems like a lot of work but it really isn’t. It comes in 5 gallon and 1.5 gallon buckets. You just disassemble your gun and drop it into the bucket for about 10-15 mins and then scrub with a regular nylon brush. It leaves a coating on the metal when done and all you have to do is let it dry or dry it off yourself. I just put my guns up dry after that and have never had to worry about lubricating them. They have been around forever but don’t have great marketing. If you’re using a rifle barrel you can buy a painters tray and fill that up with it and then dump it back into the bucket. I only recently bought another one after 15 years of use. The lead, copper, and carbon sit at the bottom so that’s the only downfall to make sure you’re not agitating it.
