Zusammenfassung:	A body panel component 51 of a vehicle comprises a first surface 26 and a second surface 28 respectively comprising a first coating layer 52 providing a first reflectivity and a second coating layer 54 providing a second reflectivity, wherein the first and second reflectivities are substantially matched, preferably for incident electromagnetic radiation of a predetermined frequency greater than 76 GHz. The second surface coating layers may comprise a reflective layer that is preferably a metallic or pearlescent paint comprising reflective particles or may comprise a self-supporting film. The second surface coating layer may include a primer coating layer, a colour coating layer and a protective coating layer. The overall thickness of the component is preferably an odd integer multiple of one quarter of an effective wavelength of incident electromagnetic radiation. The component may be a bumper panel component (4, 6, figure 1). An antenna installation comprises the body panel component and a radar antenna 2. In a method of surface treating a body panel component of a vehicle, a reflective layer may be added as a fluid medium.
