a panel assembly and method for manufacturing the panel assembly , especially adapted for use in vehicles , includes a panel of predetermined size and geometry wherein a surface of the panel to receive a gasket is primed using a material especially adapted to prepare the panel surface to bond with the gasket . the desired gasket profile is molded separately from the panel from a polymeric material . following formation of the gasket , the panel is located thereon and pressed into intimate contact with the gasket for a prescribed period of time . the panel and attached panel are removed as an assembly . additional or optional steps may be followed including preheating the panel and primed surface prior to bonding to shorten the cycle time and improve adhesion . moreover , heat may be applied to the contact boundary between the panel and gasket substantially simultaneously with the application of pressure . the steps of heating and applying pressure may be repeated to insure proper adhesion . the panel assembly and the method of manufacturing the panel assembly are especially adapted for use in flush mounted panel assemblies wherein the gasket is fixed only to a single surface of the pane and allows for gradationally varying cross - sectional profiles to specifically suit a needed application .
