I have a POR catalog and they show placing a piece of plastic wrap over the can before putting the lid on to prevent hardening.
Also, a woodshop teacher from 1969 had us tap the lid of shellac with a mallet and then turn the can over for a second to seal the lid area. I've done this for years now and have opened can years later to find many products still useable.

Also after opening the can for the first time you have to be sure and seal it again correctly because if air gets to the product it?ll harden and you?re out $$$$. A trick to eliminating the air in a paint can is to place clean pebbles in the paint to bring the paint level up to the rim. Then with the lid on, virtually no air exists. In addition, I store my paint cans upside down. This also aids in keeping air out of the can.
