Can two year prehistoric dampen platform polyurethane semi-gloss finish jump unpromising?
Answers: All paints have a shelf vivacity of one to two year depending on how it is stored Temp 60 to 80 deg F and unopened. if opened they will move about bad within less than a year again depending on temp. If it get frozen or to hot for to long period its no well-mannered.
if it was ever allowed to freeze, it's already desperate. if it looks ok and isn't lumpy, it may be alright. however, i wouldn't risk putting it on something i care in the order of. if it turns out to be bad it could be deeply difficult to remove.
