Looking into the soar energy rejecting tints i found an old test pdf which was very interesting to read and see the results. Test was by 3m in 2001 for their SRF tint (solar rejecting tint) and they saw an average of a 6.5% in reduction in AC required to keep the cabin comfortable and a resulting 1.3% fuel economy gain. Now I've tried to find specs on their SRF tint vs the crystalline Tint but i can't seem to find it. Synopsis of the report said that as time goes on the air conditioning plays a greater and greater effect on fuel economy and from what I've seen on the new prius with its windshield, and having 40% crystalline on the civics driver side window that stuff makes a HUGE improvement without the reduction in visibility. Anybody know the TSER on SRF tint? I figure the windshield, hatch, driver, and passenger window will be 80% of my heat gain so I'll just mix and match tint to get the most tser reduction for the money. 3m also noted that 3m color stable is similar to ceramic tint without the signal interference.
