How to install film on a rear side passenger door window on a Mercedes 300

Method 1: Taking them out and reinstalling them isn’t actually necessary 100% of the time. Instead, you can save time by shrinking it and tripping the door up before bottom loading it. If you’re not comfortable yet with bottom loading, then you can try doing a two-stage install. The seals aren’t that tight on these windows, so as long as you’re careful not to crease the corner angle, you should be able to gently slip it in. Method 2: Trick the door, roll back the window down to just where it touches the bottom rubber, and then try a bottom load installation. You can let the film bunch up a bit on the bottom edge if you need it, and then squeegee it upwards before slowly working the bottom down.
