Strangely enough I've just started printing today from some oiled paper
negs I made for gum some months ago. Despite my scepticism, the first
printing has come out well-nigh perfect despite my "hit and miss" approach
to exposure ( as a test, I just added 50% to my usual inkjet neg exposure).
I printed the negs, oiled them lightly on the back with canola oil using a
brush, left them overnight to soak up the oil and then blotted them off.
I've been storing these ones in copysafe pockets ever since, (about 3-4
months) and they show no signs of deterioration whatsoever. The cost is much
less than an inkjet neg. As I'm on a student budget, this is very good news!
