When the hardener goes in it is already disolved and has no difficulty
flowing with its vehicle through the matt. Here,we're talking about
flushing in solvent, having that solvent melt and absorb the hardener, and
at the point when the hardener is liquid and ready to move, hoping that the
solvent still has any velocity remaining.

I really should hop into my micro-travel space ship, shrink it down to
.002" tall and fly in for a look. Two years ago on this list, I dreamt out
loud about hardener pellets dyed black (and of the identical formulation as
keytop material) so that we could actually watch the flushing action
happen. Mind you, whatever the dye is,it must remain bonded to the
hardener.If not, our experiments would be observing the movement of dye
rather than resin.

Take a lacquer-ball hammer, set it crown down on a mirror, squirt in some
acetone, and wait to see hardener show up on the glass. I'll try it this
weekend.

We've got something in common. Why we'reall on this list. Muchos thanquos
for your ideas.
