Open the lid .. blow in a little propane from a torch .. close the lid.
Propane, being heavier than air will sink to the bottom, effectively
keeping the oxygen away from the putty, which needs oxygen to cure/dry.


Of you could simply store the cans upside down.

How would storing the can upside down stop the air already in the can
from starting the curing process ??
