I have found a product called plastic gloss made by nova industries. You spray it on and leave it. It make you plastic look brand new. The scratches are still there but not visable and it shines like brand new. Also it forms a barrier so that the next time you clean your bike the mud and dirt just falls off. Highly recomend it. It's made up here in Canada so you know it's good.
