I needed to go to Castrol's website to get some information and this popped up: "Chosen by NASA: We're proud to support the Artemis Programme with our space-grade lubricant, Castrol Braycote."

So I gotta know: what's the deal with this stuff? I found someone who sells it, although I suspect you don't get next-day shipping. This is what they say...

Braycote Micronic 601 EF is designed to operate in the presence of rocket fuels, oxidizers and high vacuum. It is frequently used in space applications including the Space Shuttle and satellites. It should also be considered in any application where a hostile chemical or extreme environmental conditions would preclude the use of an ordinary grease. Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-rings and elastomers. Perfluorinated greases, such as, this product, exhibit excellent shelf life due to their intrinsic inertness. this Micronic product is the 'ultra clean' version of Braycote 601EF.

Price per pound: $3633.75.

Amazon sells it in four-ounce syringes for $1671.99. Their description says it's non-toxic and nonflammable, with no CFCs used during manufacture...which would make it a fine grease for many interesting applications if it wasn't $400 per ounce. The seller is the same one that is selling pound cans of it on their own website...maybe they're the only firm in America that has any?
