Once you have restored clarity to your headlights, maintain them with Meguiar's Headlight Protectant. It acts like a sunscreen barrier between the plastic and harmful UV rays that cause damage and yellowing to your headlight plastic. Use every 2-3 months to maintain headlight appearance.

Apply with a Meguiar's Soft Foam Applicator Pad, or a Meguiar's Polishing Cloth.
