I like that idea Alvin. I might add that outfits like Smooth-On sell dry Nitrogen in aerosol cans because the epoxies spoil quickly also once they are opened and exposed to the atmosphere.
Nitrogen is heavier than air and a little squirt into the can before sealing it back up lengthens the life of the product. Some (not many) paint stores also stock it for the same purpose.
I like the hole in the lid and tape idea or maybe a rubber cork?
