viscosity and resistance to friction and heat should work well with a 
properly designed rotary damper. STP doesn't release what its actual 
viscosity is. As you know it is designed for a oil additive to fight metal 
to metal contact and to reduce viscosity break down as heat increases. I'm 
sure there is a study somewhere that would give the fluid that you are 
looking for, I looked briefly and didn't find your answer.
