I had what may have been the crummiest looking headlights in existance. I had tried to polish them with 2 different products and still no joy. I finally took them to my local body shop guy and gave him $200 to fix them. This was my last step before spending $900 for a set of new ones. I didn't expect much but much to my surprise they were able to make them look better than they had in years. I am not handy. If you are not handy either then take it to someone that is.
