perfect pattern of what? ive never tinted a window myself so im at a loss. we had a guy come and tint some windows in our home and he was tellin me about tinting car windows.
dot tint is no darker than 30%......i was told that by TxDOT and remember that the glass has some tint in it (don't beleave me open the window and hold a white paper next to the glass with part of it above the glass).... so don't go darker than 27%
