OK, thanks to all here :-)
I ordered the 4' x 125' reflectix from home depot and had time to cut one piece for the rear window and this stuff WORKS !
Overkill to get this much, but I have a west facing garage door that is a perfect place for the extra!
Thanks again from our quickly cooled 5th in HOT canton, tx .
If you really are sad and think nobody cares, just try missing a few payments !
