Car headlamp lens polishing

Harry Bloomfield · 2017-08-07T11:06:42+00:00

All modern cars suffer the headlamp lens's becoming opaque, its easy to clean them and polish them up, with a fine abrasive - but what then? They don't seem to remain clear as long as the did originally so do manufacturers coat the lens in something, to prevent the UV and atmosphere attacking the lens? Would the clear lacquer spray as used by car painters do the job, or might it attack the lens? Are the lens's polycarbonate?

For £30 I'd expect something better than: "Meguiar?s proprietary coating prevents re-oxidation for up to a year!" Note the "up to" - where have we heard that before!

True. My guess is to get a decent coating that works would require a factory process - like spraying - to get something invisible that lasts.

I suppose the OP has checked it's not possible to buy new lenses?
