If it's any consolation, I feel your pain. I foolishly bought a gallon tin of Zinnser shellac (I didn't know better then!) from Masters. It was the first time I'd used shellac and I was pretty disappointed that it was taking so long to dry. Live and learn and throw money into the bin I suppose.

I have heard the shelf life is 3-6 months from mixing....

I admit mine also came out of the can.. I doubt I helped anything glopping it on thick... It took a year (not figuratively - 12 actual months) to dry all the way so it wouldn't print... It was dry to touch the day I brushed it... But it just stayed soft forever... But since it did dry - it has been fine..
