parts stores (napa autozone) carry headlight and plastic restorer kits that come with like 5 different grades of sandpaper and like 3 compounds and a polish, they seem to work well. nothing blue magic makes will help you out, and i doubt the eagle 1 pads are helping much if they only last a week, they make it look clear till the polish fades. wetsand with like 3000 grit then use heavy - medium - light compounds then a good plastic cleaner/polish. thats if u wanna do it right
u can get replacements for like $300
