Tips on stretching the side panels in the back. I have fold/wrinkles.

I feel for you. Not sure what Chrysler was thinking about having the rear glass panel attached blindly to strips before attaching to car.

I guess the installers got really good at it. Mine had 2 installers, one on the left and one on the right. The right hand guy was neat and malicious, left hand guy sloppy cuts, staples all which way.
I wish my back glass unzipped from the top.
