Oh Boy, when it comes to tint the whole DIY thing is out the door for me. I brought my 1999 Trans Am & 1981 Truck to Ziebarts to have them done. I just got a quote for my GP for $300. It's a bit steep but the warranty is the kicker. After about a year on my Trans Am I got a wear mark on the tint and they replaced the driver side tint at no cost. They have my business now.
