its not that hard, if your somewhat handy and have some common sense you can do it. look up directions on google and watch videos. theres tons of sites that have instructions with videos, use baby shampoo in a 1:10 ratio with water, spray it on the window and the tint, youll have enough soap to slide the tint around and seperate creases, squegee it out and dont roll windows up and down for a few days. it is VERY easy to get it perfect if the windows are out of the truck. i never did it untill my truck and it looks just like my friends from a shop except he paid 120 for 2 windows, and i paid $29 for the entire thing
