I wouldn't use the mineral oil/bees wax mix. It's made to soak into wood and would probably be pretty sloppy on the non-porous metal.
My shop is in a metal machine shed with a dirt floor so I'm in a similar situation. I used to use Johnson's paste wax and it was ok, but it needed to be re-applied quite often during heavy use.
A while back, there was a discussion here about waxes and Firemedic (I think) recommended Renaissance Wax for planes (both wooden and metal). I picked up some several months ago and started using in on all my planes, saws, and anything else with metal that might rust.
I am very happy with it - it lasts a lot longer during heavy use (friction reduction) and after this extremely wet, rainy spring, I've not had any problems with rust. Using other paste waxes, I was constantly having to reapply and still ended up with rust if I hadn't used a tool for a couple of weeks.
It is expensive, but a little goes a very long way. After multiple applications to 8 saws and 4 planes, you can hardly tell that any has been used. I figure the little jar (200ml) will last me about 5 years.
