When I first became involved in competitive shooting I received a bottle of Prolix lubricant. I had been round shooting for the majority of my life, had worked firearms retail and spent countless hours cleaning weapons while in the Marine Corps, so I was leery of the flavor of the week cleaner/lubricants that have taken over. This bottle sat in my range bag for a year "just in case," until after a match I was talking to a good friend who is a 3 Gun Nation Pro Tour shooter and a law enforcement trainer. We somehow began discussing how neither of us had been "lube guys," he asked if I had tried it. After finding out I had not he informed I needed to. On his next visit to town he brought me some "presents" a 64 oz. jug of Prolix Lubricant Total Gun Care Product and several 1.25 oz. Prolix Xtra-T Lube. He told me the big jug works great to use in sonic cleaners. So I returned home and filled my Harbor Freight "el cheapo" sonic cleaner and went and grabbed two very neglected AR-15 bolt carrier groups. One was out of my all around and competition Limited/Factory rifle the other out of my Tac Optics/Practical match rifle. Both were in serious need of a thorough cleaning so I figured this would be a great test of the Prolix. The first bolt carrier I ran through was the Tac Optics/ Practical one, It is a SLC Super Light Chrome unit and had a few hundred rounds on it. I dutifully took "before" pictures ran it through several cycles (the "el cheapo" only does 8 min cycles) removed it and took my "after" pictures. I then ran the other bolt carrier through this is and old Colt full auto unit that has had many many thousands of round fired by it, It was very dirty and carbon coated. The SLC bolt came out clean enough that no further cycles in the cleaner or attention were paid to it. It did still have a small amount of carbon build up on the tail of the bolt but not enough to cause me any reliability concerns. It was reassembled and run through several more matches with no issues. The Colt unit was run through several more cycles due to its extreme carbon build up. After removing and its "after" photoshoot it was inspected, I found that there was still carbon present but the amount was greatly diminished and it was the carbon that I usually scraped to get off. It was reassembled and was run through a few more matches followed by a week long carbine course with US Border Patrol it too has had no issues. After seeing some very positive results i decided to try my Smith & Wesson M&P in it. This gun was almost as dirty as the Colt bolt carrier group and had heavy carbon build up around the sear and in the frame in all the hard to reach places. The pistol came out much cleaner and smelling like oranges (did I mention it's a citrus based cleaner?). The problem I found was that the interchangeable back strap had become warped (some idiot forgot to remove it) now I have to say I believe this was a result of the sonic cleaner heat feature being turned on not the Prolix. Just for good measure I cleaned my 6" STI Limited gun before a big match using the regular Prolix. It worked very well and the gun cleaned up quickly and easily. It ran flawlessly at the match which is always a concern with a 1911/2011 with tight tolerances. Now i must say I'm not a Prolix expert or a representative of the company so I couldn't tell you every aspect of it and what it is supposed to do but what I do know is that it soaks into the metal and helps maintain lubricity. From what I'm told it also gets better the more/longer you use it. So what did I think? I liked it...ALOT especially for those parts that see a lot of carbon and are hard to clean. Its not something I would have concerns using on a fighting gun such as a Glock, M&P or AR-15 and it also works well on guns with tighter tolerances such as competition guns. So overall I guess you could say I'm a fan and will be straining my sonic cleaner and reusing (yes you can do that with Prolix) for as long as possible.
Update 11/01/2015: I used nothing but prolix products to clean all of my firearms before the 2015 Surefire World Multigun Championship. It worked awesome and they all ran great even with a great deal of dirt and dust floating around. I did not clean or wipe down the guns for the entire three days I shot and I fired close to 500 rounds of rifle, 500 rounds of pistol and 350 rounds of shotgun birdshot and slugs. It worked great and I have no hesitations to do it again.
