Got a tube of Haynes CIP-Film keg lube from Amazon. I like that it washes off with hot water. Don't like greasy gunk getting everywhere. I'll use it for the mouths of the 1/2 gal mason jars on my CO2 Harvester (they leak air if the lids aren't lubed).
Thanks, @marc1 for bringing up the CIP-Film in another thread.
