Definitely some good info... this was the first thing I think that needs to be done on our recently acquired SSEi! They look terrible!

Auto Zone carries a 3M / Headlight Lens Restorer Kit (part number: 39008 ). Costs about $20 and results are AMAZING! Did mine in about an hour. Didn't need any "UV protection" either. Months later and still lookin good!

If you need to do the job on the cheap, you can get most of the results by using polishing compound and a buffing pad on a drill. Polishing compound is less harsh than rubbing compound and removes less plastic and provides a good shine. You can get a buffing pad at Walmart for about $5.00 and polishing compound costs about another $5.00. So for about $10.00 and some patience, you can achieve some pretty good results. That'* what I do when I detail vehicles.
