Super polish

All headlights have a very thin clear coating over the lens to protect it from the elements just like the clear coat on your car’s paint.  Due to the material that the headlights are made of , the coating does not last as long as it does on your car’s paint.  Over time that protection breaks down from the heat of the light, the sun and other elements causing the headlight to look like there is a fog inside of the lens.  In reality, it is the outside of the lens that needs to be restored.
