Going tomorrow morning at 9am to get my windows tinted. Any advice on what % to get. 2002 GPGT which is "Dark Tropic Teal". I am getting the Formula One brand, the guy at the place said that is the best brand he knows of and it has a nationwide lifetime guarantee. Here in ohio the legal limit for the front windows is 50% but that is hardly anything. i know quite a few people with darker tint than that and no problems so i am planning on getting either 38% or 30% for the front two and 15% for the back windows. Anyone suggest other wise or agree? anything would be great ....
