Good afternoon

I'm trying to figure out if adhesive/sealant is required between the rubber gaskets and the metal edge of the corner windows, back window and front window.
I've searched here and looked in my manuals with no luck. Still fighting with the door window sweeps, but that's an entirely different problem! As usual 1 step forward-2 (sometimes 4) steps back!

Thanks
