A deflector assembly for an automobile sunroof (60) has an elongate acrylic visor (40) for, deflecting air from the sunroof and, a pedestal (150a) mountable to each end of the visor to form the deflector assembly. Each of the pedestals is secured onto the automobile, such as with a clip (155) and fastener (156) arrangement, to removably retain the visor adjacent the sunroof. Gaskets (48, 49) are provided as a buffer between the deflector assembly and the automobile's roof, and an inert material (48a) is placed adjacent the visor to avoid adverse reaction with the gasket material (48b).
