Headlights have a heavy clearcoat on them...pay attention when you sand them, you can see when you go thru it.....using a buffer on them will remove it as well. Once you've cleaned them, they restain very easily. I pulled mine out and shot them, but this does pretty much the same thing without removing them from the vehicle...looks like a good product to me. (don't get this stuff on the car or cladding...you won't be happy, it won't come off)
