If you’ve ever had restored headlights before, you’ll know that after you’ve sanded and polished the headlight lens, it is imperative to applying a coating. Otherwise, the headlight lens will yellow and haze back up again within a matter of time. I recently restored a set of headlights on my car and needed a headlight coating. I purchased a spray bottle of Meguiar’s Keep Clear Headlight Coating and it did a superb job at coating my headlight lenses.
