I use the products from KG Industries (10+ years) and have been very happy with it. They have a rifle/pistol pack out now, and those are the products I use. The copper remover, bore polish go a long way...and don't need to be used every cleaning. The spray cleaner is what I start with...then go from there depending on what I'm cleaning and what ammo was shot. Haven't had a problem with rust, even in humid FL... the bore looks outstanding after running the cleaner through it...then followed up with an oil patch...ect....until you pull a clean patch through.
