the head light cover looks like someone put sand paper to it and lately its turning yellow. i'm not sure how to fix this.

 

I just bought my SRT Coupe with 11,300 on the car. The salesman told me that this is a problem with the Crossfires and would order new lenses. Sound like that might be the only fix. My daughters 350Z has the same problem. The yellowing seems to be from the sun and I'm not sure if there is a sun screen for headlight covers.

 

You might want to try some Meguiar's PlastX plastic cleaner/polish. It works pretty well.

 

What he said...

It cleared mine up like new. If yours aren't too far gone, then it should do what you need it to do...
