Clearcoat for headlights?

[sandman77]

I spent yesterday afternoon refurbishing my car headlights. They were badly scratched and foggy. I wet sanded with 600 then 1500 paper then used my machine polisher and some fine compound to polish them up. They are lovely and clear now and I would like them to stay that way.

I assume now though that any UV protection has been removed from the headlights and I am wondering what is best to put on them. Does anybody have any recommendations for a product I can buy for this purpose? Obviously needs to be UV resistant and non-yellowing (and heat resistant?).

I bought some of this over the weekend, arrived today. Goes on easy enough. Time will tell if any good :

This is not suitable for polycarbonate surfaces.

Are not most headlamps today polycarbonate?

Yes they are almost all lenses are PC with hardcoat on top.

Really you need a kit specifically designed for headlight restoration - but most of what's available doesn't come in can, is for professional use and you need a spraygun, compressor, etc to apply them.

By using 'any old stuff' you run the risk of solvents in the product attacking the PC - which will result in the lenses crazing and/or yellowing over time.
