Abstract: A one-piece composite mirror sail is disclosed for an associated vehicle that eliminates use of metal brackets. The sail includes a glass run that extends from beneath a belt line of a vehicle door window opening and extends above the associated belt line. A first portion of the glass run is an extruded EPDM first portion that extends from beneath the associated belt line. A second portion of the glass run is located above the belt line and is molded thermoplastic only. The first and second portions of the glass run are integrally joined, preferably along a fusion bonding interface. A coating is preferably provided on a base and seal lips of the extruded portion. An angled leg extends from the glass run second portion. The angled leg includes a retaining portion. The angled leg and retaining portion are molded thermoplastic only.
