    confused Headlight Restoration ?

    My 54 plate Vectra's headlights are now looking crap - the top 20% has gone greeny/yellow (like verdigris) and was wondering if these "Headlamp Restoration" kits are OK or just a gimmic ??

    http://www.meguiars.co.uk/product/39...storation-Kit/

    I've heard that some people wet sand them back, so apart from new units what is the best way forward ?

    I use Megs products for cleaning my car and now the headlights are letting it down

    I wet sanded the headlights on my GFs Honda last weekend and they came up like new. Light output is better as well now

    Its not as hard as you might think either.

    Before you try wet sanding just try polishing them with cutting compound and a machine polisher.

    The 3M kit is very good. If you have a DA, try what DasArab says above. If you dont have a machine polisher then I think your are kind of stuck. But with a bit of effort you can get them looking spot on with wet and dry and a bit of cutting compound.

    I have a DAS6 and a Dremel with pads, I've also got a small array of polishes and comounds too.

    After looking at the headlights the main area of concern seems to be the top 15% of the headlight.

    There is no detrimental affect of the beam intensity just a naff looking headlight.

    What causes it - wax, polish etc as it's possible that it's where I've waxed the car (being carless with the applicator and getting some on the headlight) ?

    I have this issue too (52 plate vec) and am planning to have a crack at the How 2 in the not-too-distant-future.

    Personally I think this is caused by road grime (inc salt etc) gradually breaking down the surface of the lights. I have xenon main beams so the washer solution/heat combination may also be a factor on mine...

    It most probably is caused by the tiny bits of soil, sand, grit, salt kicked up by vehicles in front of you, firing into the plastic headlight covers at 70mph leaving tiny pits, leading to the dull appearance. Over time the pits get algae growing in them, causing the greenness.

    The reason why some people's headlights suffer more than others is probably down as much as anything to how clean the roads are where they drive, how fast they drive, and how close they drive to the car in front.
