Canola oil will never dry, nor will any ordinary vegetable oil. Any oil
will lift any oil soluble marking pen ink from the clear leader. I am a
woodworker, and have about 40 years experience doing custom finishes,
using all sorts of plastics, varnishes, and oils. There are oils for
furniture finishing which will dry, but they would take many days, or
even weeks, to dry to the extent that you could roll them up on a reel
of film, and maybe not stick. They would also lift the marker.
For the effect you are trying to do, I think your best bet is to use
spray cans of CLEAR (not matte/satin) WATER-based varnish, to spray
between layers of marking pen. Go easy, or you will clog up the
sprocket holes. Let it dry, then put on your next layer of marker.
After that dries, try pinching film to film, to see if it sticks,
before you roll up the film. Even then, I would keep the film well
ventilated for several days.
Throw that canola oil away. Nasty stuff, even for cooking. It's a
variant of rape seed oil. Use olive oil or peanut oil, both tasty, and
high in monounsaturates. :)
