as far as window tinting goes, i would personally have it done professionally. cutting around the edges and everything else is a pain by itself. now i dont know what you're tinting? but i helped my buddy a couple years ago in his cherokee sport, and we started with the back window, that was such a pain by itself, that we decided to scrap the whole idea, and he went and got it professionally done. for a first timer, attempting it yourself would def be cheaper, but i'd ask around to friends to see if anyone has experience and would help you. cause you'll just end up getting mad at everything if you try doing it yourself.
not that its impossible, just very time consuming, and if you're a perfectionist like i am, its never going to look right if you do it by yourself.
