I've been on Tubliss since the begining and used everything for a lube/sealer. I have settled on elcctrical cable/conduit pulling lube. Works great for everything Tubliss, including initial liner and tire mounting. Semi dries to a waxy consistancy. Clean, cheap, and compatible with rubber/plastics. You don't even have to clean up the rim/liner when changing tires, just paint more on with a brush. Problem with tire sealants is they can dry in clumps on the inner rim and liner and need to be fully cleaned out when changing tires. This stuff is very slick, and allows the liner and even tight fitting beads like on tubless trials tires to slide out of the drop center and seat quickly and evenly. My MMH sealed perfectly first time and has held for weeks now.
This is of course if you don't need a sealant, which in my experience is useless for something like a torn knob or big gash.
