I'm considering getting my new car's windows tinted, not for appearance sake but to possibly help with the intense summer heat here in Fresno, and would appreciate any advice from folks who've had this done. It's my understanding that the interior door trim panels need to be removed for this. I'm in California, so tint on the front side windows is illegal. I am considering a medium tint for the rear door and back windows, but wonder if there's either a very mild tint for the front doors or if there's a product that cuts UV with little or no noticeable tint that I could get away with here in CA. Also, my car lacks that gradually tinted band at the top edge of the windshield and I was wondering if anything similar with a gradual tint is available. All I've seen in this regard are solid non-graduated bands of tint material added to the top edge of the windshield which looks a bit tacky imho. Any and all help appreciated.
