How To Restore Your Headlights

how to restore headlights

Do your headlights not shine quite like they used to? Most headlight covers are made from a polycarbonate plastic. Polycarbonate plastic is durable, scratch-resistant, and impact-resistant. But, over time, UV rays degrade the outer layer of the headlight and cause it to cloud over.

While it is easy to replace the whole headlight unit, it is also expensive! Fortunately, the degraded outer-layer of the plastic can be restored very easily and inexpensively. We recommend the 3M Headlight Restoration Kit. However, you can restore your headlights by making your own kit!

Tools Needed:


  • 1000, 3000, and 5000 grit sandpaper
  • Spray bottle
  • Microfiber cloth
  • UV sealant
  • Elbow grease

How To Restore Your Headlights

  1. Workin’ at the Car Wash – Washing your car before you begin will help remove any surface grime and dirt.
  2. Wax on, Wax off – You will be using an abrasive compound, and you don’t want it to to get on your paint. Water droplets and the abrasive compound are less likely to stick to a freshly waxed surface!
  3. Tape off the crime scene – Use low-tack painters’ tape to mask the area surrounding your headlights to protect the paint from the abrasive compound. Pay special attention to trim with chromed metal or chrome-finish plastic as the abrasive compound can destroy the chrome.
  4. Elbow Grease – Affix the 1000 grit sandpaper sanding disc to the foam pad, wet the headlight lens and the sandpaper, and circularly sand the headlight. Wipe Clean.
  5. Elbow Grease Pt. 2 – Repeat step 4 with the 3000 grit finishing disc, and then the 5000 grit refining disc.
  6. Seal the Deal – Apply the UV sealant. If you don’t use a UV sealant, your headlight will quickly oxidize again and you will be back at step 1!
