ABSTRACT:
A prefabricated vehicle window having an exterior molding is prepared by (a) placing a protective film inside a glass support fixture having a cavity to line the cavity; (b) depositing a bead of a first hardenable polymeric material (first bead) on top of the protective film in an amount sufficient to fully cover the marginal edges of the outer surface of a glass sheet subsequently placed on the glass support fixture; (c) placing a glass sheet having exposed side surfaces, inner surface and outer surface on the glass support fixture, with the outer surface facing toward the glass support fixture, and at least a portion of its periphery pressing against the first bead which causes the first bead to conform to the shape and contour of the film-covered glass support fixture cavity and cover the adjacent exposed marginal edges of the outer glass surface, and squeezes out any excess first bead over to the exposed side surfaces, thereby partially or fully covering the exposed side surfaces; and (d) depositing a bead of a second hardenable polymeric material (second bead) in the glass support fixture in an amount sufficient to cover the marginal edges of the glass inner surface, and the glass side surfaces.
