How bout i mail ya a tube? My business uses it in production, Ive never really had to go online to try to find it..
Now ive never looked at the MSDS or the material properties, but this stuff has the consistency of liquid dynamat, and its a nasty oil-black, when it cures its tough and rubbery. And it has a low elasticity rating (from my own tests).
I usually smear this stuff to fill cracks or gaps, and then on the interior of boxes, coat with pure resin.
