Priston Posted July 24, 2020 Share Posted July 24, 2020 Fiat X250 headlamps. I have been using headlamp protectors but on removing same have found the base vehicle headlamp lenses very cloudy. Referring to the internet I deduce this is due to UV and recommendations are to use wet and dry papers to remove and re-instate a smooth surface. I have used 1200, 3000, 5000 and 7000 grade papers (all used wet) and then polished using a Fenwicks polishing compound. The result whilst better than it was when I started is not back to pristine condition. I spent a significant time at each of the stages. Do any of you have any further suggestions?

globebuster Posted July 24, 2020 Share Posted July 24, 2020 Yes, you didn't go coarse enough! I have 'knocked off' the degraded upper layer with 600, then stepped up to 1200. As far as polishing goes - try 3M Fast Cut or Mirka Polar Shine. They'll come up lovely, but you may still find slight crazing within the substrate - and there's not much you can do about that.

Keithl Posted July 24, 2020 Share Posted July 24, 2020 I agree you need to start slightly coarser. The AutoGlym headlight restoration kit starts with 800 used on an electric drill. https://www.autoglym.com/headlight-restoration-kit Keith. Link to comment Share on other sites More sharing options...
Gman Posted July 24, 2020 Share Posted July 24, 2020 Did mine last week, using the Auto Glym resto kit, 800 down to 3000 plus paste, 2 1/2 hours each side results are fantastic. Sorry can't post pictures on here. Hope this helps. Steve Link to comment Share on other sites More sharing options...

I'd second this no quick fix to protect mine I keep aluminium foil between the protector and head light when not in use But for a quick none lasting fix WD40 will do the trick Link to comment Share on other sites More sharing options...
Charles Posted July 25, 2020 Share Posted July 25, 2020 A friend of mine used Harly wax on his and said they came up like new, although his van is only a couple of years old. Try it as a finisher. It's fantastic on paintwork and faded bumpers too. It's got carnauba wax in it B-) Link to comment Share on other sites More sharing options...
Derek Uzzell Posted July 25, 2020 Share Posted July 25, 2020 I use Bilt-Hamber wax https://www.bilthamber.com/double-speed-wax https://www.autoexpress.co.uk/product-group-tests/63776/best-car-wax-and-sealant-2020 and, although this produces an excellent finish on shiny surfaces, it has none of the abrasive properties needed to restore headlights. (It's also been my experience that, although restoration is certainly possible, it's unlikely to offer a long-term solution.) Link to comment Share on other sites More sharing options...
John52 Posted July 26, 2020 Share Posted July 26, 2020 Vim powder does a decent job, and is safe on plastics Still available in Spain, but I don't think you can get it in UK now It was replaced by cif, a watered down version. Link to comment Share on other sites More sharing options...
