Subject:OT: Fatar keyboard action lubricant

A little off topic as this affects the weighted TP40M action in my Nord
Stage 76 (but it does have the Electro Hammond model)...

I've got a key that is sticking - A below middle C. As you can imagine,
this is really annoying. If I thump it from the front and push the key hard
to one side then it sorts itself out mostly for a couple of songs. I'm now
doing all my gigs (mostly piano) solely on my Kronos 61 and making copious
use of octave shifting. I've taken the thing apart a few times, and I've
worked on Fatar actions before, so the likely culprit is either a slightly
bent finger the rises up in the middle of the key, or a lack of lubricant.

Anyway, I have two questions:

1. What is the lubricant? It's a thick paste of some kind, but googling
comes up with a lot of contradictory posts on various forums, and from
experience I know that spray on silicon lubricant isn't sufficient.

2. Should I attempt to sand/file down the rubber on the finger that holds
the key in position?

Many thanks!
