A trim panel-water barrier subassembly for vehicle structures includes a film of water impermeable material attached to the panel and a seal (of foam or other resilient sealing material) about at least a portion of the perimeter of the outer surface of the water barrier. The seal may include a treatment on its outermost surface, and preferably a release liner is employed to facilitate shipping and assembly of the trim panel.
