Peeling clear coat on headlights is a common issue that can affect your vehicle's appearance and light output. This guide will walk you through the process of restoring your headlights to their former glory.

Understanding Clear Coat Peeling

Clear coat peeling on headlights occurs due to prolonged exposure to UV rays, harsh weather conditions, and environmental factors. This damage can lead to reduced visibility and a deteriorated appearance of your vehicle.

Assessing the Damage

Before starting the repair process, it's crucial to evaluate the extent of the peeling:

  • Minor peeling: Localized areas with slight lifting
  • Moderate peeling: Larger areas with noticeable flaking
  • Severe peeling: Extensive damage covering most of the headlight surface

Preparation

Gather the following materials:

  • Sandpaper (800, 1000, 1500, 2000, and 2500 grit)
  • Masking tape
  • Microfiber towels
  • Isopropyl alcohol
  • Clear coat spray (2K automotive clear coat recommended)
  • Polishing compound
  • Polishing machine or drill with polishing attachment

Step-by-Step Repair Process

1. Clean and Prep

  • Wash the headlights thoroughly
  • Dry completely with a microfiber towel
  • Mask off surrounding areas to protect from overspray

2. Remove Peeling Clear Coat

  • Start with 800-grit sandpaper to remove the peeling clear coat
  • Use light to medium pressure in circular motions
  • Avoid sanding too aggressively to prevent damage to the base plastic

3. Progressive Sanding

  • Move to 1000-grit sandpaper
  • Continue with 1500, 2000, and 2500-grit
  • Ensure even sanding across the entire headlight surface

4. Clean and Degrease

  • Wipe down the headlight with isopropyl alcohol
  • Remove all sanding residue and oils

5. Apply New Clear Coat

  • Shake the clear coat spray can thoroughly
  • Apply 2-3 light coats, allowing each to dry for 10-15 minutes
  • Maintain proper distance (about 6-8 inches) while spraying

6. Allow to Cure

  • Let the clear coat cure for at least 24 hours
  • Avoid touching or exposing to moisture during this time

7. Final Polishing

  • Use a polishing compound with a machine or drill attachment
  • Work in sections until the entire headlight is glossy
  • Wipe clean with a microfiber towel

Preventive Measures

To prevent future peeling:

  • Apply a UV-resistant sealant or ceramic coating
