Yes, Autosol or any other metal polish, such as Peek or if you want to push the boat out White Diamond, T Cut will not cut through the damaged layer.

WD leaves a decent protective finish, but you must apply generous coats of wax polish to the lenses afterwards because you've removed the original coating, and you will probably have to give them a light polish every year from then on as even with wax on the sun will cloud them again gradually.

I've never needed to resort to using wet and dry glasspaper which i see others use.

Course if the clouding is on the inside no amount of polishing will fix it, unless the lenses can be removed.

Never needed to polish proper glass lenses BBD (the ones on the old MB are as good as new @ 24 years, yes i meant plastic lenses the blinking awful things.

I know that White Diamond stuff is expensive, but in its defence a small amount goes a long way and it leaves some sort of hard protective sheen which Autosol and Peek don't, the only thing with WD is that if you don't use the bottle for a long time the contents can separate and take some remixing, if you get some its worth putting somewhere it gets seen regularly so you can give the bottle a shake now and again.

Peek cuts well, as does Autosol, both can be bought from various places in 500ml or 1 litre cans, a lot cheaper method of buying than in the small toothpaste sized tubes.

I can recommend this kit, used it to refurbish a used motor cycle headlamp unit as an alternative to buying new at approx £500 each!

Depends how bad they are. If they just need a bit of a freshen up then a good MOP with some cutting compound used with a polisher can often do the job.

Alternatively if you have some P1500 handy you could rub them down with that then give them a polish up with come compound followed by a final gloss polish.

I've just done the headlights on my d-i-l's car, which were dreadful. I used some Turtle Wax headlight cleaner and sealant (can't remember how much it was) on a polishing cloth. Gave a pretty good result in a few minutes with not too much effort. Seems to have just about the right amount of 'cut' to get the job done. Would recommend it.
