Valuable lesson learned about Silicone Caulk

[Giles]

I have a bathroom in my barn/shop and the vent pipe had a small leak with a few drips coming down. I have used MANY tubes of Silicone Caulk, over the years, and I am aware of the "shelf life"
In the past I found that even an unopened tube will set up after so long, so I had a tube that was soft and didn't look at the date
I crawled up on the steep roof and found a small place that I suspected was the problem.
The Silicone was soft as new but had a strange consistancy and I suspected it was beginning to set up.
I should have stopped because this was applied over a week ago and it is still WET
I noticed this on a rag I used for cleaning, I looked at the tube and it expired in 2005
This was GE-- 100 percent Silicone Seal
I just came down from cleaning off the 1/2 tube that I applied to the whole outer surface. Took over an hour :thumbdown:
A stupid mistake that I will not make again :ashamed:

You won't do that again in a hurry!

I'm a laid back kinda guy when it comes to expiry dates, which was proved when I bought a Water Purifier from a recycling store a week or so ago really cheap and it came with two water filters. The only catch was that the filters (according to the packets they were in) expired in July this year!

Well, I put one in, and the water tastes great and the filters work fine.

But, I draw the line at years! :laughing:

Yeah--If I had looked at the date, I would have thrown it away. Just strange that it was soft and not SET UP. Never had that happen before.
