you would be pretty suprised on how nice some of the new ceramic based windowfilms are. I have some on my 79 with no a/c and you cant feel the heat of the sun on your skin when the windows are up. look for a llumar window film dealer in your area and ask for there ctx film. kinda pricey compared to regular dyed films but well worth it if you are lookin for heat rejection. There are other nice brands too like 3m and solarguard and suntek cxp is pretty good also
