DIY Automobile Headlight Restoration

DIY Headlight Restoration | Pretty Handy Girl

I have found that most of my driving is done when it’s dark outside.  I get up pretty early to go into the firehouse and on my drive in I tend to notice things around me, things like how bright my headlights are compared to other vehicles on the road. What surprises me is how many vehicles have cruddy looking headlights.  Nowadays most headlights are made from plastic.  It’s cheaper and more durable than it’s glass predecessor, but the disadvantage is that it’s prone to oxidation.  In simpler terms,  over time, ultraviolet light from the sun, breaks down the plastic, causing a hazy or yellow film to appear.  It lessens the effectiveness of your headlights and during the day, makes your car look bad.  Luckily, 3M Car Care makes a DIY Headlight Restoration Kit to get your headlights looking as good as new!

The Kit Contains:

  • 1- Disc Pad Holder
  • 1- 3M™ Automotive Masking Tape
  • 1- 3M™ Soft Interface Pad
  • 6- 3M™ Sanding Discs
  • 4- 3M™ Finishing Discs
  • 1- 3M™ Trizact™ Disc
  • 1- 3M™ Headlight Lens Polish
  • 1-Buffing Pad

What Else You’ll Need:

  • Drill
  • Spray Bottle and Water
  • Safety Glasses

Here’s the condition of the headlight that I’ll be using in my restoration.

Headlight in Need of Restoration

Start by masking off the area surrounding the headlights. (For demonstration purposes, I’ve added a strip of tape in the center of the headlight.  You won’t need that on yours)Divided Headlight

With the work area prepped, secure the disc pad holder onto your drill. Place one of the sanding discs onto the disc holder pad. The discs are held in place with velcro.

P500 Grit Sanding Disc

Begin sanding in the center of the headlight, allowing yourself time to get a feel for how the drill will react. You’ll only need to apply light pressure to backside of the drill.

Headlight Restoration Sanding

The goal is to remove the imperfections on the surface of the headlight, so continue to sand until you feel satisfied that you’ve removed the oxidation.  Once the sanding is complete, the headlight should have a coarse, frosty appearance.

Next, switch out the sanding discs for the finishing discs.

P800 Grit Sanding Disc

Switching to the finer grit sanding disc reduces the coarse sanding scratches from the previous step.

Remove the used finishing disc and replace it with the Trizact™ disc.

P3000 Grit Trizact Sanding Disc

Using the spray bottle of water, you’ll need to wet the Trizact™ disc, along with the surface of the headlight during the next sanding process.

Wet the Triazact Disc

You should begin to see the scratches from the previous two steps become much finer and the headlight should start looking clearer.

Headlight Restoration Final Sanding

Replace the Trizact™ disc with the orange foam compounding pad.

Apply a dime sized amount of the lens polish to the pad.  To reduce the chances of making a mess, smear the polish onto the headlight before engaging the drill. Repeat as necessary until any cloudiness is gone and the headlight is clear.

Here’s a side by side comparison once the center strip of tape has been removed. (I repeated the same steps as above to match up both sides of the headlight.)

Headlight Restoration Side by Side Comparison

Remove the automotive masking tape and using a buffing cloth, apply a dime sized amount of the protectant to the headlight surface.  The protectant acts as a barrier between the lens surface and the ultraviolet light from the sun.

Here’s a quick glance at the headlight before and after the restoration!  It’s a pretty substantial difference!

Before-and-After-Headlight-Restoration

The entire headlight restoration took under 30 minutes and I’m confident that these headlights will light my way much more effectively than before, plus they’ll look good for miles to come.

Of course, there are other ways of restoring headlights, but from my experiences, the 3M Headlight Restoration Kit has given me the best results; was the easiest to do; and lasted for the longest period of time.  This is not a sponsored post, nor did 3M supply me with this kit.  I’m just a firm believer that when I find a product worth using, it’s a product worth sharing!

Happy and Safe Driving!

    This is an awesome tutorial, Matt! I live in Florida, so I’m no stranger to the sun causing headlights to turn a nasty yellow color. I’m in desperate need of replacing my headlights altogether, so I’m currently looking at buying an HID kit from HIDExtra (for extra brightness, and I have a friend who’s handy with cars). I’m going to keep these tips in mind though for keeping my new headlights looking sharp!
