Jon, Like I said, I haven't even had the cab outside yet, but hot sun is something we don't see a lot of up here. I did have a soda can blow up once when I left it on top of the dash of my DD truck. Kind of a mess.

I'll be sure and update the group on how the 7708 performs.
As far as getting 3M to make you a generic version of their 08059 stuff --- good luck with that.
