I found the sticky post of comparison tests of various products very helpful, but it didn't include one of the products that I recently discovered: Microlon Gun Juice. It is advertised as a superior dry lube, but also as a rust inhibitor. See http://www.microlon.com/
I didn't have a good way to test lubrication, but testing rust prevention is easy. I had some old, blued sling swivels laying around and saturated one with Gun Juice, and another with Rem Oil. Then, I hung them outside until I had a chance to get back to them--about 2 weeks.
The Rem Oil treated piece had very little rust, the Gun Juice treated piece was very rusted. See pic below.
In short, don't trust expensive Microlon Gun Juice to protect your expensive firearms. And Rem Oil ain't all that great, either. Plain ol' WD-40 worked better.
