in union, nj had one of my car tinted there way back. great work! dont know what film they used.
The Tint Shop, on Rt 1 in Edison NJ did great work as well. paid about 200 i think for the most basic one. they had madico film which is top of the line.
if you want cheaper, Boom Boom II in Palisades Park does good work i've heard, and seen a few friends rides tinted there. i def know its cheaper than the previous two I mentioned. I would ask what tint film they use and go online and do research on it.
sidenote: NJ is cracking down on tints. If you are gonna get it still, go light... 35% - 40%
