Mostly and FYI post. Every so often the subject pops up in this NG. My
story:

Bought a cartridge tube of white GE Silicone II at Blue Borg in March
2008. Expiration date of 10/2008. Didn't use it but kept it. A few days
ago I had a need for some caulk around a shower and opened it. Suppose
to skin in 30 min and dry in 24hrs. Days later it's still even surface
tacky.

I had the opposite problem with the same product. Bought 2 tubes in a
row that were dried up in the tube, even though it was before the
expiration date.

They just have bad batches sometimes.
