I am going to be using my KBS products for two different jobs a few months apart. Is the BEST way to store KBS by cleaning can ridges, covering with thick plastic wrap, sealing the lid and refrigerating? How about freezer (or is that overkill)?

Taken from the RustSeal Directions:

DO NOT PAINT OUT OF CAN! It is recommended to use quality brushes but at disposable prices as cleaning them afterwards is difficult. After a good stir, dispense a working amount of RustSeal into a separate container (steel or glass is best) and seal original can immediately. Unused paint should NEVER be put back into the can as it will shorten its shelf life and cause pressure build-up possibly popping the lid. Keep can groove free of paint by using a scoop or KBS Paint Spout. Use heavy plastic wrap between the lid and the top of the can to stop metal to metal contact as RustSeal can permanently seal the lid. If there is any trouble resealing the can lid tightly, transfer and store RustSeal in another proportionally sized can or glass jar. Always store paint in a cool dry place. RustSeal may be refrigerated for storage but you must allow paint to reach room temperature before re-use.

The key in all of that is not painting out of the can and keeping the time that the can is open exposed to the air to a minimum. You can absolutely store in a fridge but just make sure the paint gets back to room temperature before you use it.

Please let us know if that helps and if you have any additional questions.
