My AI just called to see if I had any Aeroshell #6 grease. I don’t. Apparently there is a production problem (fire?) that won’t be resolved until spring, according to a supplier I contacted. It’s a prop grease. So if you are sitting for a case or two, now is your chance to cash in. The supplier said Aeroshell might know of an alternative. Fortunately it’s not a current need of mine.
