I have some OPENED Mainstay bars that have been in my car for over 4 months in 95degF heat(in the shade! The inside temp is usually WAY over 105degF). I am planing on opening it up and trying it in another month or so(say a prayer for me...) <img src="/images/graemlins/blush.gif" alt="" />

I was told that AFTER opening, that it is good for weeks(I THINK that is what they said!)

This experment was NOT planned... I just found some that I had opened and used half of, and forgot it was in the car.
It has been in a Glad ware soup & Salad container all this time and a lot of it in the back window in the sun, so this should be a pretty good test...
I will report as soon as I get the courage to open the container and smell it <img src="/images/graemlins/grin.gif" alt="" />
