Yellowed, hazy headlights make a good car look tired and genuinely reduce how much light reaches the road. Restoring them is one of the highest-impact jobs we do.
Headlight lenses are polycarbonate with a factory UV coating on the outside. Melbourne sun breaks that coating down, and once it fails the plastic underneath oxidises — which is the yellow, cloudy look. Supermarket restoration kits polish the haze off but leave the plastic unprotected, so it goes yellow again within months.
We wet-sand the lens back through progressive grades to remove the failed coating and the oxidised layer entirely, machine-polish it to full clarity, then apply a proper UV-stable protective coating. That last step is the one the kits skip, and it is the only reason the result lasts.
It is also a very worthwhile job before selling a car — clear headlights are one of the first things a buyer reads as ‘well looked after’.
