As a reminder: Loctite prints a lot number on the bottom of each bottle which gives the date of manufacture. That date code can be decoded as:
YDDDxx
Where Y = the last digit of the year: 1 = 2011 2 = 2012, etc
DDD is the sequential day of the year: 30 = 30 January, 40 = 9 February, etc
Freshness matters!
My 2 cents,
