Just to add my 2 cents... I replaced two lift trims this past weekend. One was really rusted to the glass and one was not. I used an old post card to work the area between the glass and trim channel. I slid the card edge in carefully and then went back and forth slowly. Once I felt the trim start to loosen in the center (left to right) I just kept working the card back and forth. Eventually, I was able to maneuver the old trim and pull it off.

I was afraid to use heat, liquid or a blade.

I carefully cleaned the edge of the glass with some water on a cloth and then dried it immediately. I let the glass sit to make sure it was 100% dry and then I installed the new lift trim. I hope to never mess with these glasses and trims again.
