Cool.....yeah its not too hard to do, if you diy, make sure you put enough on and give yourself enough to cut without a problem! Also, take your time....it depends on the type of tint you use, I went the cheaper route and picked up that self tint from Wallyworld in 5% and put it on myself with really no problems....and its still on today and looks excellent! Just be sure to get all the air bubbles out and make sure its really wet.
If I am wrong, I apologize and anyone please correct me!
I Take it its not for your camaro.....seeing as you stated "2 back seat windows"
