Atleast its confined to the valance pan. Maybe a good bodyman could repair the damage,and with todays computer matching you could do a straight enamel blend. Just make sure that you leave the original color showing on the edges where it meets the fender. Maybe you could also if it dosen't blend as well as you hoped it would,you could test some clearcoat with a flattening agent,on some testpanels until you achieve the correct sheen that the original finish had. It would be a lot easier to blend the damaged area with basecoat,and then cover the whole valance with the low sheen clear coat.
