Just a quick heads up - my headlights were starting to get some oxidisation marks on them, so I decided to clean them up.

I wasn't sure on the chemistry, so I took a punt on this product: Pittman ALR APC 7cc Acrylic Plastic Headlight Cleaner Deoxidizer Conditioner | eBay It works amazingly well, and removed the marks really quickly without damage. Worth trying before destroying the original UV coating.
