Minwax Polycrylic - How long is it good for?
I have a half-full gallon of Minwax Polycrylic that I bought and used about 3 years ago. I live in Illinois and it has been stored in my garage, which is not temperature controlled. I am starting on a new staining project and I opened the Polycrylic up and it still looks fine, but should I be hesitant to use it? It isn't worth ruining my work if it is no longer good, but at the same time I would hate to go buy a new can if the old one is still fine.

I've had a gallon can of Polycrylic for 5 years that I tap into now and then for various projects. Of course, I keep it in my basement which is cool and dry. Maybe try some on a scrap piece of wood to be sure it's ok.

Some things can withstand a freeze- others not so much. If you opened and stirred it and it looks OK- it probably is. They get weird when they go bad- usually not hard to tell.
.. Try not to freeze this winter- don't press your luck!

Ditto what Brushjockey said.

If it froze and heated up to Midwest temps in the garage, I would error on the side of caution before using it on a large project. I most certainly would strain it into a new can. Then try it on a small sample to make sure it still cures. There are few things as pure fun as trying to get a non-cured sticky finish off of something.
