    I have just polished my headlights and are happy with the outcome.
    Should I clear coat them?
    For and Against please.
    Cheers

    If you can find a headlight UV clear coat, I would try that.

    I've polished many pairs of cloudy head lights, tried to seal them with a UV sealant, but they usually start to get cloudy again after a few months.

    yeh same

    I used marine grade UV clear coat and after a like 6months started to yellow

    Once they start to yellow, can never permanent fix

    I found headlight restorer and once a month Turtlewax Headlight Cleaner and Sealant to be pretty good

    This makes sense as when the plastic is originally moulded it would be hot.
    Never heard of this but very interesting.
    Thankyou.

    This is the problem when manufacturers use components suited to Europe or cooler, less UV intense environments than ours.

    I don't think any manufacturer makes plastic headlight lenses that won't discolour or fade over time in our climate. Good old glass had a lot going for it.

    I couldn't agree more. Not made to last, just cheaper to make and will need replacing.

    I am thinking about clear coating them. What type of clear would you suggest? What about a plastic adhesion promoter?
    My biggest fear is melting the plastic throw a bad reaction.
    Cheers for your input.

    I've done it with colorspec crystal clearcoat. No adhesion promoter, just make you sand the lenses back well to avoid reaction with any previous coatings.

    buy new ones while you still can (originals not chinese eBay junk) they'll be good for a lot longer. If they haven't already GM will stop making these. As a plus new ones come with a full set of globes. :)

    I tried this method and even got the same Clear at Bunnings.
    Came up great after first spraying then rubbing back orange peel then applying a second coat.

    Awesome thankyou.
    I watched the video you posted and bought the same brand paint at Bunnings and cost $20 total, paint and the iso cleaner.
    Thankyou for your help.
