heres what i did i j ust got the finest grit sandpaper i could find ,600 grit , and sanded the light as good as i can and sprayed some glossy clear coat that is uv resistant. it works great. now i see more light when driving and the lights look like new now. but usuing some brake fluid is a good idea before sanding to get rid of the old faded coating. i found out about this method from my friend the guy that painted his car used the same method and his lights look real good now.
