(OP)
I would be grateful if some information on the shelf life of the ULT 372 Glass Polyester Thermosetting Varnish can be provided (old product line from sterling-tech.com ). We had purchased a large quantum of same over 5 years ago and are experiencing rapid hardening rate before use. This usually cause great difficulty for the motor rewinders.

Somebody could also be adding too much catalyst because they want to work faster or be misreading the directions. If you have 2 different concentrations of catalyst vials confusion can happen.
