An assembly (10, 10') includes a substrate (12, 12'), a trim member (14, 14') and a heat-activated adhesive member (16, 16'). The substrate defines at least two surfaces (18, 18') including a finished surface (18a, 18a') and an unfinished surface (18b, 18b'). The trim member defines at least two surfaces (20, 20') including an outwardly-facing finished surface (20a, 20a') and an inwardly-facing attachment surface (20b, 20b'). The inwardly-facing attachment surface of the trim member is arranged over and trims the unfinished surface of the substrate. The finished surface of the substrate and the outwardly-facing surface of the trim member form a cooperating finished surface (24, 24') of the assembly. The heat-activated adhesive member is disposed over both of the unfinished surface of the substrate to the inwardly-facing attachment surface of the trim member to indirectly attach the unfinished surface of the substrate to the inwardly-facing attachment surface.
