Hi & thanks!
I've put some around the mirrors, and down the C-pillars (to be extended down further), so far. I should also do the A pillars I think. It's back to commuting tomorrow, so I see if they make any noticeable differences.
The cooler weather (and rain, requiring some defrost/AC action!) has caused my FE to drop a bit -- the tank I put in today yielded 44.31, which dropped my 90 day average from 46 to 45.9mpg...
