A method of affixing a gasket to a transparent substrate utilizing a fixture having a channel formed therein, into which the gasket is inserted and held in place by, for example, a vacuum. Alternatively, a removable form may be inserted into the channel, and the elastomeric member/gasket is inserted into the removable form. A suitable substrate is precisely positioned on the fixture in a predetermined position relative to the elastomeric member. An adhesion promoting primer may be applied to the substrate, and an adhesive may be applied to the gasket, or to the substrate. The elastomeric member is then bonded to the transparent substrate. Finally, the completed assembly is removed from the fixture.
