Use plastic epoxy. Kinda tricky to match the color but hides 100% of the scratches. Look on ebay youll find one. if not google it. Most of local auto part dont carry it. One suggestiong when you mix to match the color apply it to some other plastic and leave it for few days to dry. once dry it changes colors. Best thing to do mix 6 or seven combination and let it dry at same time. once dried pick the best match and use that forumula. hope it helps.
