Rated 3.0 out of 5.0 by Expired Product I had the same issue as one of the reviewers, who was told it might be expired. I did some digging online, the code is: Example: 8183AS 8 = Last digit of year manufactured 183: = Julian Date AS: = Random to distinguish between lot numbers So, I was able to determine that my product, bought 3/25/15, expired on 6/4/14. It's going back tomorrow. April 2, 2015
Rated 1.0 out of 5.0 by Too Thick This stuff was way too thick to actually be applied as a caulk. It basically came out as plastic. Threw away the open tube and returned the second one. December 10, 2014
Rated 5.0 out of 5.0 by High Temp Application I installed a new Aprilaire 800 Series steam humidifier in my house. I needed a product to seal the the steam injector spray head into the ductwork. This was the least expensive of the 2 choices (same brand) that were handy for immediate purchase as I was in a hurry to get the job done. The product worked flawlessly and after 3 weeks, no sign of leakage. It did it's job well. January 15, 2014
