Yep, I prefer moly-based dry lubes too; but as you say, they're exy.
I do keep a few reasonably exotic versions of these on hand [as my usage is very low these days], but they are usually way too exy to buy for one-off jobs.

Except where they are essential to prevent rapid failure of expensive bits, e.g. the splines on motorcycle drive shafts.

'PTFE' is the generic acronym [for PolyTetraFluoroEthylene], but 'Teflon' is still a registered DuPont trademark, BTW.

Cheers,
Gadge
