This Guy Used Polyurethane Sealant on his Windshield/Rear Window Gaskets

I bet the newer designed gaskets were made to facilitate installation on the line, Glue 'em in and get them on down the line! Gojo (no grit) hand cleaner is a great installation tool, Lanolin makes the (old) rubber slickery and pliable. EZ clean up too. window and lock strips just pop right in. Id do windows again in a heartbeat over a headliner install, F that!
