It's interesting that Pete and I had exactly the opposite experience,
which often seems to be the case in alt processes. I started with
vegetable oil and found it to be sticky and it started to smell after a
while, so I switched to mineral oil and found it to be just the ticket
for me, never going sticky or rancid, and neither drying out nor
remaining too oily on the paper, as well as having a pleasing feel to
the hands. I haven't tried sunflower oil specifically, but used a
generic vegetable oil. I would suggest that beginners to oiling who want
to use a vegetable oil stick with Pete's recommendation of sunflower
oil. When I open up a box of my paper negatives oiled several years ago
with the generic vegetable oil, the rancid smell about knocks me over,
I'm not kidding.
I waxed some negatives this spring and found waxing not to be
satisfactory for me. It may be a specific incompatibility of the wax
with the paper I use (Epson Photo Quality Glossy Paper) but I found that
the waxed negatives scratched very easily, marring the final print.
