Headlights on the Volvo have got UV damage and I've got a kit (Visbella) that supposedly will get them looking like new. Once done, I would like to put some protective film on them so i'm not doing the job again in 2 years time. Does anyone have any recommendations. It's got to be suitable for headlights (correct refractive index I understand). The Ebay stuff, albeit cheap from China, doesn't convince me that it's right.
