Contact the manufacturer -

“Generally” epoxy has an indefinite shelf life IF it is kept under decent conditions (no temp extremes, etc.) Almost all epoxy systems are 100% solids so there’s no solvents to worry about evaporating or reacting with air/moisture.

Just my opinion & everybody’s got one.

It can pull in moisture and harden up though Bob. 02-03 isn’t that old though. I have tested older epoxies and they just take forever to cure.

yeah I would call the manufacture on that but I think you might be ok
