BMW 1992 M3

The vertical gasket by the rear view mirror is to tight to slide the tint under so once I had applied the tint and made it flush with the gasket, when you close the door the entire window moves toward the rear of the car about 1/8th of an inch creating a gap with the tint and the front gasket. Anyone experienced this?
Thanks

over cut both the sides about a 1/4" . before u install, grab the glass and yank it toward the back. apply film. door glasses tent to shift...its your duty to manipulate it.

Thanks

When the door opens and the window moves forward is the tint gonna want to slide under the rubber?.....seems pretty tight on the window
