Rear window molding

[gapost]

So I have a crew cab with a leak from the rear foldout window. Yes, I know about the hinge issue. But on mine, I found that the plastic molding around the edge of the glass is loose in a couple of spots along the front edge of the window, letting air in while driving. I am thinking about trying to glue this. Has anyone seen specific problem and been able to fix it? If so, what glue or adhesive?
