Start off with the 500 grit sand paper with a drill and brush the surface of the headlight. Make sure you supply ample amounts of water on both the pad and headlight. Eventually the headlight will become cloudy and that’s simply because of the yellowing being sanded off.

Rinse off the headlight and make several more passes. Make sure to wet both the headlight and pad again. The headlight will start to become clearer but we’re far from done.

Now you’ll have to buff the headlight by using the supplied rubbing compound. Start with small dime sized amount and slowly buff the headlight as low-med speeds. Continue until the compound becomes dry. Once you consider your headlight good, you can remove any excess rubbing compound. The result will be a nearly fresh headlight!
