New To Tinting

So I have decided that I wanted to learn how to tint my windows and my friends windows. I have decided to start on Dodges because thats what i have and most of my friends. How hard is it to tint a 2007 Dodge Ram 2500 Crew Cab w/ slider? I have read not to heat shrink? Is that correct? Thanks for the help.

not too bad once you know what your doing. just keep trying it out on yours first untill your satisfied with the results, then do your friends.
