Are there any thermal resistance specs for the lithium greese?
How thin a layer can you put down?

With the thermal grease you usually use a very thin layer ( a few mils)
just enough to fill any air gaps due to surface imperfections. Lithium grease
seems like it would be a lot thicker.

You could do a thermal resistance test but by the time you get setup
and calibrated your next-day Digikey order will have arrived ;-)
