The reason yours look yellow.
Modern headlight lenses are polycarbonate, not glass. They come from the factory with a thin protective UV layer. After a few years of equatorial sun that layer breaks down, the polycarbonate underneath oxidises, and the lens turns yellow or foggy. Polishing alone removes the haze but does nothing about the missing UV layer — which is why those quick jobs come back yellow within a year. Our process fixes both.
How we do it
Surrounding paint and trim taped off so we don’t catch anything with the sanding step.
Starting at 800 grit and stepping through 1500, 2500 and 3000 grits. The lens looks worse before it gets better — that’s normal.
Compound first to remove sanding marks, then a finishing polish until the lens is optically clear again.
Surface cleaned with the recommended prep solvent so the new clear coat bonds correctly.
Two thin coats of automotive-grade clear that replaces the factory UV barrier. This is the step that makes the result actually last.
Cured under controlled heat, inspected for runs or imperfections, and reassembled.
What you should expect
- Lenses noticeably clearer with measurable improvement in light output
- Result that holds for at least 18–24 months under normal sun exposure
- Free re-spray within 12 months if the clear coat fails on its own (very rare)
- If the polycarbonate is cracked or the inside of the lens is fogged, we’ll tell you up-front — restoration only fixes the outside surface
