I kept paint upto 3 years. 32 deg paint for example. I had stuff that was 3 yrs old and looked like pyramids. still shot though.
I have 8 bags of paint that range from 4-7 months old right now from time i bought them, but no idea how long they sat in the store. And theres no problems with any of them.
