Re: SPI Shoutout
If it's been sitting that long the solids have likely settled some. Stir it with a stir stick to get solids mixed back together and then mix up a small batch with the hardener to test. (The hardener is what will likely go bad if anything) Let it set a few days in 65+ degree heat to see if it starts to harden. If it hardens, great. If it doesn't, replace the hardener.
I've had some sit that long without issue.
