ditto on using meguiar's plasticx

mine were yellow on the top closest to the hood

bought some plastic x and after two or three washings and elbow grease they looked as good as new

also if you put plastic x on when they are clean they will stay nice and shiney! guess it is kind of like wax for plastic.

it costs four or five bucks at the auto store and is definitely worth a try first. you can also use it on other stuff besides automotive so you really wouldn't be wasting your money anyway and you might save the money and time and hassle of installation.

 

this thread may have saved me money, mine are yellerin', going to have to try this.thx
