Tapio,
My mistake. I meant 8,000 to 9,000 cts.

I have not had a problem with dry knots, then lubing afterward with this
thick silicone.

Thermals,
Don

I have been using thick silicone fluid for quite a few years for F1B
motors. Made by Dow Corning, it has viscosity of 14,000 centistokes (and
looks like rather thick syrup, thicker than maple syrup for instance).
I've also used stuff of 500 to 1,000 cts., this also works, but it is
spilled of the motor more easily. (I wonder if your figure of 80 to 90 cts
is correct?). BTW, I use a knot that needs to be lubricated when tied,
otherwise it will cut throught the rubber, but I have found out that
1000cts silicone is better for wetting the know. If you use the thicker
stuff, the knot will slip and fail when stretch-breaking-in the motor...
