Does anyone have experience removing varnish from a painting? I varnished a painting last year with Gamvar gloss and I guess I stood the painting up vertically too soon afterwards because the varnish ran but I didn't realize it until it was fully dry. It's not real noticeable -- only noticeable in full studio light, but it does bother me. If there's an easy way to remove it without much risk of damaging the painting, I'll probably give it a try.
Thanks for reading.
