Has anyone tried this stuff (or similar) for sub-chassis damping?http://www.quietcoat.com/
It seems like it would bond to surfaces better than Dynamat.
Follow Ups:
I bought some last fall to try on my old GENESIS II rebuild. The stuff is a very thick paste and works to absorb vibration. Several different formulas are available.

The trouble with doing nothing, is that you can't tell when you are finished.
When I built some Dynaudio Speaker Kits many years ago I coated the inside of the cabinets with a black heavy tar-like automotive undercoating, which worked very well in damping structural resonances in the cabinets.
This looks like a total nighmare on elm street.I use vinyl sound deadener from PartsExpress. This has sticky stuff on one side, a semi soft vinyl that is moldable, pliable, and reversable.
I would not use a paint on product. IMHO it is a royal pain to remove.
Cheers!
By the way Dynamat is really great stuff and is easily removable.
I've neve had a problem with getting Dynamat to adhere, perhaps
in automotive applications where road grime, oil and access are serious issues.The AD copy looks good, but having been in that business you can assume it's at least 70% pure BS.
One of the really wonderful things about Dynamat is the fact that you can remove it, which IMHO is a very good thing as in my experience it's easy to over dampen and removing some restores the life and dynamics, so you end up with precisely the amount of dampening you actually need, leaving me to wonder what removing a spray on dampener would entail ?
Once I ignored User 510 advice on TD 125 dampening and my table ended up sounding like a Goose farting on a humid day.
What did you do to that innocent turntable?

Tubes- Not just a Goose Farting ! but a Goose Farting on a very humid day, which totally decimates the rich harmonic overtones and wonderful inner details one thinks typically assumes when reflecting on Goose flatulence ;-)What I did was to Dynamit the hell out of the TD 125 and damp the springs as well, against steve's (User 510's) expert advise.
The previously musical as hell TD 125/SME Series III, now sounded
flat and downright dead.
(whatever the heck that stuff's called) inside my TD160 years ago. I figured that damping was good, so...under the plinth, on the inside of the chassis, under the platter...etc., etc., etc.That was long, long before the internet and AA...probably still in the 70's.
It sounded EXACTLY as if I'd taken a heavy comforter and hung it over each speaker! I removed one strip of the crap at a time...eventually I took it all off...except for the new light sponge rubber stuffed into the springs...the stuff that had come when the table was new (or...now that I think of it...was that me???) had turned to crumbly dust (I wonder what the MJ smoke was doing to everything else?).
So, now that I wrote a completely unintelligible sentence, I'll explain: I went back to how the table had come to me when brand new!

Henry I did indeed, I spaced out notifying you, sorry.
