Factory headlight lenses leave the production line with a thin, sacrificial hard coat applied over polycarbonate. That coat carries the UV inhibitors. Sunlight, road salt, wash chemicals and thermal cycling consume it. Once it is gone, the polycarbonate beneath begins to oxidise directly — yellowing, hazing and micro-pitting until light scatters instead of projecting.

Consumer restoration kits attack the symptom. A quick abrasive pass and a wipe-on topical clarifier will look convincing for a few weeks, then the haze returns worse than before, because the failed coating was never fully removed and no new barrier was bonded in its place.

Our hypothesis is simple and testable: if every compromised layer is removed in a controlled progressive sequence, and the refinished polymer is immediately sealed under a ceramic barrier, optical clarity returns to factory standard and stays there.

We test that hypothesis on every vehicle. Documentation before, verification after. The six stages below are the experiment.
