It may be good, may be not. But it would suck to have to strip it all off. I once used a can of epoxy primer that had been opened 6 months earlier, then re-sealed. It never would cure totally. The supplier said it was because it had a limited shelf life after opening. It was really a pain to take it all back off.
Nowadays I spray a test patch and see how it goes. I recently painted my wheels with a 20-year-old can of acrylic enamel when a test spray showed it performed like new.
