It's this stuffBrand??
Have you ever tried to emulate the 'kitty hair' that is in stans. I don't know what it is, but it certainly sinks to the bottom of the quarts (need to constantly shake them to keep the particles in suspension). If I just pour the stans off the top without shaking, it does not work nearly as well IMO. It makes a lot of sense to include some sort of material/matrix to form the 'clot'.
Carpet fuzz?? roadie leg hair?? landing strip trimmings??? chopped fiberglass??

I know guys that have put glitter in stans to get the same kind of platelet effect. I've never needed to using this stuff. Couldn't hurt I guess.
