ATM Vibration damping

["Fred Maxwell - No spam e-mail accepted." <fmaxwell@erols.com>]

Having seen several comments regarding vibration, I thought I would pass
along this thought:

There are products made for the car stereo industry to damp vibrations.
The big brand name is Dynomat.  It is sold in sheets and is about 1/8"
thick and self-adhesive.  The stuff is amazing.  The demo I saw had two
5" (or so) paint can lids suspended by strings.  One was normal and one
had about a postage stamp size piece of Dynomat.  If you struck the
normal one, it rang like a bell.  The Dynomat one made a dead "thunk"
sound.

I'd be interested in hearing if anyone has used this to damp telescope
or mount vibrations.
