Has anyone done just the ubtibted portion without having a visible line? I’m getting mine delivered next week and if I can avoid doing the entire back window I’d like to. Looking to do 20 in the rear, 40 up front, and 70 on the windshield. I swear I saw a thread somewhere that someone had success just doing the untinted portion. I feel like 20 on top of the factory tint is overkill and I should just put vinyl up there. Thanks in advance.
