I would think some of the Dow Corning viscous fluid in a viscosity range of,
as I recall, 25000 to 50000 might be great. It's viscosity is very stable
over a wide temperature range and does not appear to evaporate after years
of use. (We used the stuff as a damping fluid in some disk cutting
equipment at the recording studio. If anyone has knowledge of a
Scully/Westrex cutting system dash pot, you'll know what I'm speaking of.)
