My "shop" refrigerator is not for storing food. I do a lot of personal custom CF/FG composite fabrication, hoods, trunks, shrouds, diffusers, spoilers, etc.
Purchasing the resins/epoxies in larger quantities keeps costs reasonable. The problem is the liquids seldom have a shelf-life thru experience and manufacturer claims of more than a year. I have extended that to over 8 years storing the resins at 40F. All my body putties, etc are also keep within. The freezer side I keep completely stocked with .5 liters of frozen water bottles, since this is Florida and I might lose power.
