Thats great and all, but from personal experience, I was getting rust on a couple of guns cleaned and wiped down with FL in about a week, and that was in a gun safe, in a more or less environmentally controlled room.
As I said before, towards the end of my using it, it was noticeably more "watery" that it was when I first started using it, and I actually wondered if they werent cutting it with water.
I use Eezox for anything I dont want to rust, and it does work very well. I have tools, dies, and a couple of guns in a damp basement year round, with a humidifier, which helps, but things still rust if not treated. I have yet to see any rust on anything Ive treated with Eezox, and I usually only wipe things down when I use them, and/or once a year.
This was one of the first corrosion tests I saw a few years back and was one of the reasons I went with Eezox for rust prevention. I dont think FL was around yet when that was done, but from my own experience, Eezox is superior to anything else Ive used.

There were a few other tests run about the same time, and with pretty much the same results.
