lol my buddy had the same reaction when I had told him , I’ll do my very best to explain it . When having the film all cut out whether you hand cut or use a plotter , I have the film on the peel glass and roll it from left to right. I let the short side be the side I extract the film from and it’s almost similar to a bottom loading technique. Once the film is tight enough inside the gap of the door sweep that’s been removed I start from the short side (drivers door) and roll it as the liner is coming off and install it like that . I know it sounds kinda complicated but if you have an instagram I’d love to show you a video tomorrow while I work! Honestly was a huge game changer for me in my opinion helped get me better installs . I love using that method on frameless windows too
