A windshield trim assembly for stretch-forming to fit on an edge of a curved windshield is disclosed. The trim assembly has an aesthetically pleasing elongated panel and an elongated base member, which base member includes a windshield-receiving channel, a side-facing longitudinally-extending panel-receiving channel having a bottom and two sides, and a cantilevered lip extending from one side and partially over the bottom of the panel-receiving channel. The cantilever lip plastically deforms to secure the elongated panel within the side facing panel-receiving channel of the base member upon stretch-forming the combination. The elongated panel is preferably roll formed stainless steel, while the base member is preferably an aluminum extrusion. A method of stretch-forming such a curved trim assembly for a boat windshield also is disclosed.
