I just did a little quick research, and found something interesting.
The component of rapeseed oil that is harmful to humans, and has been
reduced in the varieties of rapeseed that produce canola oil, is called
erucic acid. This is actually an oil, that WILL polymerize, i.e. dry
and get hard. But, the amount of it in canola is greatly reduced. It
can be up to 60% in rapeseed oil. So, perhaps real rapeseed oil would
do what you want, or at least the erucic acid extract of it would. But,
it would still have the tendency to lift the marking pens. I think my
spray varnish suggestion is the most practical.
