Expiring Heatsink



Has anyone heard of heatsink compound going bad? I'm thinking of buying
some "Arctic Silver" heatsink compound in the future, and would like to know
if the stuff goes bad after awhile, since I don't intend on using all that
much in the current timeframe. I would hate to buy a big amount, then later
when I need it, it's gone south and is useless.
