Ok, so my friend got his windows tinted today. First I aurgued with the guy that 25% was the legal in Texas and he said 35%. I told him about the laws and everything and just gave up on him. Anyways, we got a peek at them putting the tint on, and they where putting in on, on the outside of the window. I have never seen that done before that a knew of. I believe my windows were done inside of the window. Does anyone know why they do it different ways and any pros and cons. Or maybe they do both sides?
