The recent thread about polishing caravan windows reminded me that I've been meaning for some time to restore the headlights on Mrs C's ancient Honda Jazz. I did the job this afternoon and as I didn't want to hijack the other thread, I thought I'd start a new one in case anyone else's headlamp lenses have deteriorated and they are wondering what to do to get their car through the new, tougher MOT test.

Here you can see the extent of the problem. The polycarbonate 'lenses' have started to break down due, presumably, to the effects of UV radiation.

The repair process is quite simple and takes an hour or so each side. The kit I used contains everything you need including very fine (2000, 3000 and 5000 grade) wet and dry paper; a foam sanding block; a tube of plastic polish; a spray bottle of sealant and a wad of cleaning cloths together with comprehensive instructions.

You wet sand the lens transversely with 2000 grit, do it again with 3000 grit vertically and finally finish with the very fine 5000 grit transversely before using the polish vertically and then giving the lens a coat of sealant.

This is the kit I used. (£10 from Amazon)

One down, one to go

The finished job - like new again.

I'm sure the items in this kit would also be ideal for removing deep scratches from caravan windows.

They do say in the instructions to try using only the plastic polish first but the lenses were too far gone for it to have any noticeable effect.

When I started rubbing with the wet and dry I could hear and feel the difference as the rough areas became smooth. All in all, a very satisfying couple of hours work.
