does it have a shelf life. thanks.

 

Good question. I have never noticed a shelf life for the SMR. I would estimate 2-3 years in good storage conditions.

You might want to contact 3M about that one. http://www.3m.com/about3M/contact/index.jhtml

 

sent message.

 

they say one year from date of manufacture for all waxes and polishers.

 

As said above this is from 3M:

Hmmm, I guess my "guess" was overestimated. 1 year sure seems short to me.....

Oh well, thanks for checking!

 

Ya, I am a little surprised at only one year from date of manufacture...

I bet there is a decent amount of 'expired' product sitting on store shelves, let in people garages!

 

i have their paste wax and it's 2 years old and still works great.
