I use mostly Waterlox, a product that I very much like. What is a bit disconcerting is that as a hobbyist I don't pound out the product to quickly consume a one quart bottle of this stuff and it skins over, get thick and globby and has to be tossed. I have tried "bloxygen" with limited success, and am hoping someone might have a secret or tip. Would placing the can in a zip lock bag between uses be of any help? Any other ideas?
