clean your windows well before you start...no residue, lint, and absolutely no fingerprints or oils...and dont use that cheap ass walmart tint. try and go to a tint shop and see if they will sell you some...adam, that tint you got was top of the line tint...that little bit i gave you was $40 my cost...the rolls are about 3 bills each. but as you can see its worth it. it will never discolor and should never peel, unless the windows werent cleaned well.
