I'm with you...you're right on the hardener thing, too little it's hard unless there's noit enough to even get enough of a reaction going, and a little too much makes it mush, too much more and it's a goo.

: It would be interesting if we knew the molecular structure (and diluent
: proportion) for each epoxy resin and hardener, so mixing and matching
: would be possible.

: I have mis-mixed Raka before...I thought too little hardener was hard and
: brittle, and too much was soft and flexy...which seems counter-intuitive,
: unless I have it bass-ackwards.
