Apparently they've changed the formula. Used to get thicker, now it gets thinner. I use the stuff in the bottle, not the tube.
Somewhere I have a bottle of sodium silicate or "water glass," which is the traditional sealant for brass shot shells. I'll give it a try and report back. Somebody cautioned against using it, since it's used to disable "cash for clunkers" engines--but I think the engine destruction isn't from abrasive qualities, but rather its ability to transition from liquid to solid quickly (you substitute it for the oil in the engine). Basically it destroys the bearings, etc. through binding and jamming. In a shotshell it will just break up and blow away.
Barring a miracle sealant, I'll start thinning my cushion wads a bit to make room for more sealant at the top of the shell.
