Tinting windows?

Sosa pretty much explianed the best way for someone to try it themselves. I tint windows for a living. I recommend your pull the glass out the truck it will come out cleaner for the most part and less chance of have gaps. One thing we do is with a Scott blue shop towel and some soap/water mix rub down the edges of the glass really well a lot of dirt settles in the minor pores of the glass edge.
