For anyone who has used 3M Automix panel bonding adhesive (08115), how long does this stuff last after you have opened it? I wanted to space out my workload a little but 3M has no data whatsoever on post-shelf life.

I have had it last many months.Just save the stopper and the clip that holds it in when you open the tube and replace it when your done.

aight, thanks. I got a little worried after talking to PPG; the paint lasts a year but after opening the hardener is only good for 14 days.
