I'm sure this problem has been covered elsewhere but I can't find it. I now have my third Stang and my second 2013....loved them all but for one minor issue. The gloss on the plastic read deck lid looses its gloss. Is there any way to fix this? A coat of clearcoat perhaps? It's a Roush Six (R6) so finding a replacement with the Jack Roush signature is impossible...I've been looking for years.
