Hello,

I recently purchased at HD a small tube of:

GE Silicone II
100% Silicone Sealant
Kitchen and Bath
With Bio Seal

Haven't used a product like this in many years, and am wondering if
I got the wrong "stuff," or if it is defective.
....

Might it be an "old" tube ? What's the shelf life of this kind of
product ? :

Well, the GE FAQ "thoughts"...

Does caulk go bad?
GE caulk features a "Use By" date on the bottom of the cartridge.
This should tell you if the caulk is still fresh and able to be used.
If you cannot read the use by date or want to test the caulk prior to
starting a project, there is also a simple test that only takes 10 to
15 minutes. Run a small bead on a piece of cardboard. If after about
15 minutes, the product doesn't form a "skin," the product is
probably too old and won't ever fully cure (dry completely).
