An experienced art tutor once mentioned in a video a few years ago that in addition to the other reasons to varnish an oil painting (protection from scratches, to be removable when dirty, to deepen the saturation, to even out the sheen or change it) that you wanted to varnish an oil painting after it was completely dry in order to seal the painting to prevent it from absorbing any more oxygen after this point – because it would become overly oxidised or dried out if it continued absorbing forever.
Is this correct?
Thanks!

Hi Brian
I have read every varnish post on the forums and the entire varnish resource guide over the last few weeks.
I could not find an answer to this question so wanted to see if anyone on the forum knew.
Please do a search about the use of varnish here on MITRA as well as looking over our VARNISH pdf in our resources section.
