I was thinking about those wood furniture that is coated in a thick hard resin coating, and I thought it sounded perfect for headlight yellowing problems.
polyurethane (not polyester) casting resin is optically clear UV stable, and a lot cheaper than opti-lens.
There's something called Alumilite water clear, and it costs $24 for 16oz.
That's way more than opti-lens, and it cures hard.
Sounds like a good coating for failing headlight lenses. It's sandable and polishable too.
