I received some Hysol from Vern a year ago and each container had the
date JUN 05, 2001 stamped on it. Wondering if it was still ok to use, I
spoke today to a Dexter chemist (they have been bought by Loctite
Aerospace) and was assured the adhesive is perfectly ok to use. Their
one concern was that if the product had been stored in high temperatures
(120+ degrees), then after a year it would be unreliable.

Just thought I'd pass this on.
