DIY Headlight Restoration for 1984–2004 Mustangs (Pro Detailer Secrets)

Foggy, yellow headlights making your Mustang look tired?
Good news — you don’t need an overpriced kit to fix them.
Here’s exactly how a professional detailer would do it, using affordable supplies (and a little patience).


🛠️ What You Actually Need

Sandpaper:

  • 1000 grit wet/dry
  • 2000 grit wet/dry
  • 3000 grit wet/dry
    (Buy sheets instead of a kit — you’ll save money and have extras for the future.)

Polishing Compound:

  • Menzerna 400 (8oz bottle)
    (Heavy cut at first, finishes down buttery smooth.)

Protective Coating:

  • DIY Option: CarPro CQuartz (motorcycle size)
  • Alternative Option: 2K clear coat spray (with hardener)

🔧 Step-by-Step Process

1. Prep the Area

  • Wash headlights thoroughly.
  • Dry completely.
  • Mask off paint and trim (use painter’s tape).

2. Wet Sanding

  • Start with 1000 grit (keep it soaking wet).
  • Move to 2000 grit.
  • Finish with 3000 grit for a smooth, haze-free surface.

💡 Pro Tip:
Spend extra time with 3000 grit — it saves you hours of polishing later.

3. Polish

Apply Menzerna 400 to a foam pad or microfiber towel.
Polish until the lens clears up and shines.

4. Clean

Wipe headlights with isopropyl alcohol (IPA) to remove oils and residues.

5. Protect

  • Apply a ceramic coating like CarPro CQuartz, or
  • Spray a 2K clear coat for a hardened, glossy finish.

🧹 Pro Detailer Tips for a Cleaner Job

  • Always mask your paint before sanding or polishing.
  • Sand in straight lines, not circles, to avoid swirl marks.
  • Keep the surface wet — dry sanding causes permanent scratches.
  • Patience wins. Take your time for the best results.

💡 When Restoration Isn’t Enough…

Sometimes headlights are just too far gone — deep cracks, major pitting, or broken plastic can’t be saved.
