Headlight Restoration / Sunshine Coast
See the road again
Most people think yellowed headlights are just a cosmetic thing, a sign the car is getting older. They're not. Hazy lenses cut your light output by up to 70%, make night driving genuinely dangerous, and they're a tick-the-box fail point on a QLD roadworthy. We restore them properly with a UV-sealed finish that actually lasts.
The reframe
Yellow headlights aren't dirty, They're oxidised
That cloudy, yellow-amber haze on your headlights isn't grime, isn't moisture, and it isn't on the inside of the lens. It's the outside surface of the polycarbonate breaking down from years of UV, heat, and road grime. Up here on the Sunshine Coast we get a full dose of all three. The fix isn't a wipe with a cloth, and it isn't a $30 kit from Repco. It's a multi-stage resurface, polish, and UV reseal.
What causes it
UV, heat, and Sunshine Coast sun
Modern headlights are polycarbonate plastic with a thin UV-protective factory coating. That coating wears off after a few years (faster up here), and once it's gone, the plastic underneath starts oxidising. UV breaks down the molecular structure, you get the yellow haze, and it gets worse every summer.
Why it matters
Light output drops, sometimes by 70%
That haze scatters the beam before it leaves the lens. You're still running the same bulbs, but a big chunk of the light never reaches the road. Night driving feels harder, oncoming headlights feel brighter (because your own are weaker by comparison), and on a QLD roadworthy a hazed lens is a legitimate fail point.
What restoration actually does
Resurface, polish, reseal
The oxidised top layer of plastic gets wet-sanded off in graduated stages. The lens gets machine-polished back to optical clarity. Then, and this is the bit most jobs skip, a UV-resistant ceramic or sealant goes on top to replace the factory coating. Without that final step the plastic just oxidises again.
Why DIY kits fail
No UV seal means it comes back
Repco-shelf kits and most YouTube tutorials get you a clear lens for about eight weeks. Then it yellows again, often worse, because you've stripped the original UV coating and not replaced it. The polish step is fine. The missing seal is the whole problem. We use a Gtechniq UV ceramic that's purpose-built for polycarbonate.
The process
Five stages, one proper job
Jack has been detailing on the Sunshine Coast since 2008. Headlight restoration looks simple from the outside, but the difference between a job that lasts two months and one that lasts two years is in the prep and the seal. Here's exactly what happens.
Mask & prep
Protect the paint
Tape and film around every edge of the headlight. Wet-sanding near unmasked paint is how you ruin a bumper. This is the step quick-lube places skip.
Wet sand
Three-stage cut
1500, 2000, then 3000 grit, wet, by hand. Each stage removes the marks of the one before. Skip a grit and you'll see the scratches at night when oncoming lights hit the lens.
Machine polish
Back to optical clarity
RUPES dual-action polisher with a cutting compound, then a refining polish. The lens goes from frosted-glass to crystal clear. This is where most of the visual transformation happens.
Decontaminate
IPA wipe-down
Isopropyl alcohol strips every trace of polish residue, oils and fingerprints. The lens has to be surgically clean before a coating goes on, otherwise the seal won't bond.
UV seal
Gtechniq ceramic
The step everyone else skips. Gtechniq HALO is purpose-built for polycarbonate headlights. It replaces the factory UV coating you sanded off, and it's what makes the restoration last 12 to 24 months instead of two.
Why this matters
The cheap job done four times costs more than the proper job done once
Most headlight restorations fail inside three months, and the customer ends up paying twice. Here's what goes wrong in a corner-cutting job versus what we actually do.
The cheap job
What goes wrong
- Skips the UV seal entirely. Lens looks great for eight weeks, then yellows again worse than before.
- Polish-only at quick-lube places. No wet-sand, no resurface, just hides the haze for a day.
- No masking. Wet-sand slurry hits the bumper, paint and trim. You trade headlights for swirl marks.
- Wrong grit progression. Sanding scratches show up at night when other cars' headlights hit your lens.
- Generic spray sealant from a can. Not formulated for polycarbonate, doesn't bond, peels off in patches.
The JETWASH job
What we actually do
- Full mask-up around every lens edge before any abrasive touches the car.
- Three-stage wet sand (1500, 2000, 3000) with proper grit progression so no scratches carry through.
- Machine polish on a RUPES, two-stage compound and refine, back to true optical clarity.
- Surgical IPA decon before any coating goes near the surface.
- Gtechniq HALO ceramic UV coating, purpose-built for polycarbonate, 12 to 24 month protection.
Pricing
Honest, flat pricing
Most cars and SUVs sit in the standard pair tier. Severely oxidised lenses, deeply pitted plastic or oversized 4WD and truck headlights need extra wet-sand stages, that's the heavy tier. Optional ceramic upgrade for anyone who wants the longest possible UV protection.

Save $100 when paired with a major service
Adding a headlight restoration to a Full Detail, Ceramic Coating or Paint Correction booking takes $100 off the combined total. Same studio visit, same trip, better value.
Best for
When you actually need it
This isn't a cosmetic upgrade. It's a safety service that happens to also make the car look better. If any of these sound like you, it's worth a booking.
Visibly yellow or hazy lenses
If you can see the yellowing from a few metres away, you've already lost a serious chunk of light output. Worth fixing before night driving gets worse.
Weak high beams at night
Your high beams suddenly feel useless on dark roads, but the bulbs are fine. Nine times out of ten the beam is being scattered by the lens, not the globe.
Roadworthy or safety inspection
QLD inspectors can fail a vehicle on hazed lenses if light output is compromised. Restoration is a fraction of the cost of a new headlight assembly.
Pre-sale prep
Yellow headlights are one of the first things buyers notice and one of the biggest "this car's been neglected" signals. A pair of clear lenses can lift the perceived condition by a tier.
Older 4WDs and utes
Hiluxes, Rangers, Patrols, LandCruisers, anything that's been parked outside on the Coast for ten years. The sun bakes the UV coating off and the haze sets in fast.
Night driving feels harder
You're squinting more, oncoming lights feel brighter, you're not seeing as far. It's almost never your eyes. It's the car telling you the lenses are gone.

FAQ
Honest answers
Yes, and the more yellowed they are right now, the more dramatic the difference. The bulbs are fine, the lens is the bottleneck. Once the haze comes off, all that light reaches the road again. On a properly oxidised lens you'll see a recovery of up to 70% of original light output.
The standard UV-resistant sealant gives you 12 to 24 months of protection in Sunshine Coast conditions. The exact timeline depends on whether the car lives outside or in a garage, and how much summer sun it copes with. The optional Gtechniq HALO ceramic upgrade extends that to 2+ years.
Honest answer, no. A cracked lens or one with internal condensation is a sealed-housing failure, and that's a replacement-assembly job, not a restoration. Restoration only works on the outside surface of an intact lens. If you're not sure which yours is, send through a photo and Jack will tell you straight.
No. DIY kits are usually a polish step only, sometimes with a spray-on "sealant" that isn't formulated for polycarbonate. They get you a clear lens for about eight weeks. We do a full multi-stage wet sand, two-stage machine polish on a RUPES, and a Gtechniq UV ceramic seal that's purpose-built for headlights. The job lasts 10x longer.
If your car was failing inspection because of hazed lenses cutting light output, restoration solves that. We've had cars come in specifically to clear inspection items and they've gone straight back through. Worth doing before the inspection, not after the fail notice.
We do both, but most jobs are pairs. Reason being, if you only do one side, the clarity mismatch with the other one is genuinely noticeable, sometimes more noticeable than the original yellowing. Single is fine for accident replacement matching or budget jobs, but if both are hazed, do both.
Standard pair is around 1.5 to 2 hours. Heavy oxidation and 4WD jobs can run to 3 hours because of the extra wet-sand stages. We work out of the studio at Coolum Beach, you can drop off and grab a coffee or wait through, whichever suits.
Same process works on any polycarbonate lens, so yes, taillights, indicators and fog lights can all be restored if they're hazed. Send a photo through and we'll quote per piece. Fog lights and indicators are usually less weathered than headlights so they're often quicker.
Last word
It's not your eyes, It's your headlights
If night driving has gotten harder over the last year or two, oncoming lights feel brighter, your high beams feel weaker, and the road ahead just doesn't reach as far, that's almost always the lenses, not your vision. Bring the car in. We'll restore them properly with a UV-sealed finish that actually lasts.
