Headlight restoration is essential for both functional and aesthetic reasons. It eliminates the scratchy, dull layer from the lens, improving visibility by almost 140%. Aesthetic appeal is equally vital as a well-maintained vehicle reflects on the owner’s image.

  4. Polishing: Apply a special polishing compound to restore the lens clarity;
  5. Sealing: Lastly, spray a UV sealant to provide a protective layer from the elements.

Long-term Maintenance for Car Headlights
