I'm working myself up to getting my Prius windows tinted/treated 8) and was wondering if anyone has had V-Kool 75 applied to their car. How satisfied are you with the temperature reduction? I'm not really interested in the "kewl" dark window look and it appears that V-Kool 75 provides nearly the same IR/UV reduction as HO 50 while maintaining a high light transmittance. I don't have the sat nav so reception is not an issue. Thanks.
