A finishing panel structure for an automobile comprising a trim panel, a deformable panel and a retainer bracket. The trim panel is connectable to the automobile and defines a panel opening. The deformable panel at least partially covers the panel opening, and defines a latch opening and at least one mounting apertures proximate to the latch opening. The retainer bracket defines a retainer bracket opening. At least one projection extends from at least one of the trim panel or the retainer bracket, and extends through the mounting aperture of the deformable panel. At least one engaging structure is formed on the other of the trim panel or the retainer bracket to engage the projection.
