A vehicular window assembly adapted to close an opening in a vehicle body includes a window panel of glass or plastic in the form of a sheet, a primer layer, and at least one polymeric gasket preferably formed from a polymer resin comprising an olefin and bonded to the panel on the primer layer which also comprises an olefin. The primer preferably has a transition temperature above which improved adhesion characteristics are exhibited, and the panel and primer are preferably preheated above the transition temperature prior to molding or other application of the gasket. Alternately, the primer can be cross-linkable and is preferably cured after application of the gasket through ambient moisture and/or post heating. The gasket may also be preformed and applied to the window panel with pressure and heat.
