Back glass gasket

Ugh, just did the work around my rear window over the last couple of weeks. Lower rear corners were pulled away from the body enough for water to get between the 2 pieces of the pinch...wicked all the way down to the tail lights ( this is on a Duster ) and I had to replace the trunk gutters on both sides.
Take a look at the pinch area, mine was all wavy almost all the way around so I straightened it with a hammer and body dolly and filled the edges with seam sealer so even if it does leak again, it wont suck water between the sheet metal.
