I have a few ESEE knives and have been using frog lube paste on the uncoated parts of the blade (i.e. the laser etching and the sharpened edge). No rust to speak of yet. I reapply after they've seen some heavy use or after sharpening. I think most any light oil would probably be fine for preventing rust, but will likely have to be applied more frequently than some sort of paste.
Of course, I also etched the logo on my Izula and then used some Birchwood Casey Permablue to treat the steel.
Edit to add: I almost forgot- http://www.jungletraining.com/ There's a great discussion board/forum over there.
