I spray the underside of mine with waste diesel oil, the blackness of the oil makes it look nearly painted, so it looks a little better than just spraying it with automotive oil. The oil soaks in a bit and helps it last. I should have started doing it a lot sooner because the winter salt rotted out my bedrails and my big X crossmember. Took me a while to find something to spray the oil effectively, but what works is a cheap walmart campbell hausfield sandblaster. Just stick the hose in a gallon bottle of oil instead of into the grit.
Doesn't look as purty as chassis paint, but it's free, easy to redo every season and looks much better than dry rust. And I have to think it slows up the rusting process. When I swapped the new bed on I could have painted it (the chassis I mean, I undercoated the new bed), but I had a genius idea of mixing some black Zero-Rust (same as POR-15) into the oil. Sprayed it on, looked great if a little too glossy. Didn't last though, seemed to wash off. If I had the brains to keep after it and oil it more frequently I'm sure the truck would be in a lot better shape underneath. But I load it down with sand/salt mix and leave it, sometime it's in there for a couple weeks. I rinse it up underneath every chance I get, but the roads are salty all winter here. Just can't be helped.

Just something to consider:
Used engine oil has carcinogenic elements. Aerosolizing it makes it worse.
Again, just something to think about.....

Hmm, seems to be some evidence that used diesel oil isn't - http://toxsci.oxfordjournals.org/cgi/content/abstract/13/3/545
its better to leave the truck salty underneath until spring. after the layer of salt on the metal interacts with it, the salt loses it's corrosive abilities and almost acts like a barrier for the new layers of salt. If you wash it all the time, you are only exposing fresh corrosive salt to freshly cleaned metal.
