I would NOT recommend doing a DIY tint install because there is no real way to perfectly install tint, it is not an intake or a pulley.. its more like cooking or painting.. and if you dont have skills at either of these is your creation will be an abomination.. you also don't know how accurate the pre-cut tint will be...

I had my tint installed at Lorenzo tint which is a pretty well known tinter in the New York area, various well known people have gotten their tints their as well.. It cost me $330 and I had the sides and rear tinted at 35% and the front windsheild at 50%.. the type of tint used was a hybrid to create a mixture of longevity without harming radio reception.. It is not exactly the cheapest price, but the tint was top notch and the job was done exceptionally well.. in the old country there is a saying "the cheap man pays twice"

there are a few pictures in my gallery, but they are not very high quality..
