: One question: I've heard/read that poly glues have to be used quickly after
: opening or they tend to set up in the bottle. I haven't found this to be a
: problem at all with Elmer's and my bottle has been open for over a year.
: Are the other glues more sensitive to this, or is the warning just
: nonsense?

The last 2 bottles I had did set up in the bottle after a few months. The brand was "Professional (something)". Says on the bottle "the best, the very best.
