I used this on the headlights of my 2006 model year car and it work wonderfully. I was noticing the beginning stages of oxidation, some very mild haze on the plastic. After washing and clay baring the car I taped off the area and used this product. It restored the clarity and shine. Realistically I wouldn't expect this stuff to make a ten year old and neglected car's headlights look brand new. In fact, I tried just that and it didn't work; even after sanding with 1,500 grit paper, using a rubbing compound, then this product. However, as a preventive maintenance or regular use item, I think it works superbly. It couldn't be easier to use, just follow the directions.
