I have a unopened can of resin
that been in a unheated garage
for 2 winters now.

Very risky to use based on what I've read here. A"can" or resin cant be that much cost wise, and even w/o freezing, it has shelf life. There are lots of types of resin too.

Ayuh,.... If it's Polyester, it's gone bad from Time,....
The Freezin' is also a No-no,...

Epoxy can stand alot more shelf time than poly, but neither like to be frozen,....

That is a very good and sensible question too. The only way to know for sure is to take a little bit of it and mix it up and apply it to some scrap item and see if it sets up and cures. If it does, I'd use it. If not, trash the remaining amount and repurchase... That way YOU will know for certain...

If it's polyester resin it may be ok, heat is more damaging to poly resin than cold. If it's epoxy resin throw it away, epoxy that has been frozen is useless.

Do as gm280 suggests and mix a little up and try it if it's poly resin.

hard to freeze something that doesn't have water.

I store hundreds of gallons of epoxy in an unheated garage in NH - and have been doing it for a dozen years

very possible some of you have used some of it --- I sell a few thousands of gallons of epoxy every year

epoxy is more likely to crystalize in cold weather - if so warm it up and the crystals melt (like honey)

As has been stated best way to know is to open it and try it. Ya just never know. Shelf life is a funny thing.
