glasman brings up a good point about keeping POR15. It can be done but you nee d too get your wife on board with it first because it means keeping it in the refrigerator. Oh, and put some plastic food wrap over the can so you can get the lid off. Doesn't smell any worse than last weeks lettuce.
Or... think of it in another way. This is a very good reason why you really need a refrigerator out in your shop.
