Somewhere on TFL someone did a really, really thorough study of rust prevention using many different lubes. That was a year ago or maybe 18 months? I don't have a link. Anyhow, Frog Lube did very well when compared to many other cleaners/lubes.
That said, the general skinny since has been that so long as you don't use FL for a part with light weight that has to move in a tight space (think striker channels), then FL is fine for lube/rust prevention. I use it to clean bores, frames, bolt carriers and pistol slides.
There are other good suggestions here as well.
