No you don't! Trust me, its a pain to remove when ít leaves bubbles!

Yeah, your tint shop sucks my guy. Sorry to break it to you.
A decent shop won't leave weird cut lines, won't leave bubbles, streaks, nothing. It'll look like factory tinted glass, and shouldn't wrinkle, fade, bubble, or anything. Tint's too cheap to accept bad work, literally all of the shops's price is in markup and labor.
Also, there's a ton of tricks to get it to come off easy. Trashbag trick is probably the easiest.
