I've got 20% all around. Just had the rear window re-done, $190 to remove and replace. Failed inspection in Oct 04 and still drivin around with the red rejected on the windshield, but gonna remove the front and sides this Oct, get inspected, then get retinted right afterwards. It was harder to see at night when I first got the car (it was already tinted), but I got used to it and don't even notice it any more.
