Good point, Bruce.  In that vein, the 'expiration date' is close to a =
simple arbitrary number.  In the large volume product we use, the =
manufacturer gives a 6 month shelf life statement....whether it comes =
fresh off the production line or has set for 6 month in their warehouse. =
 A test coupon to check formulation and the viability of the polymer =
components should be done anytime components have set for a lengthy =
period of time (more than a few weeks, especial as you approach, or =
pass, the expiration date).

And for those of us in the past 10 years who built planes with Jeffco
that was stored cold or on the floor. Well, good luck and hope your
plane stays together.
Wonderful news to learn of now.  Would have been nice to know this
yesteryear.  =20
