raddys Posted August 14, 2015 Share Posted August 14, 2015 Heloooo guys and girls As I'm sure many of you have experienced the joys of clouded yellow headlights.. my question to you guys is what's the best option to get them back to new? I have bought some g3 compound polish and wondering if it is wise to use this on the headlights? Any help much appreciated Thanks Quote Link to comment Share on other sites More sharing options...
Guest Andysdr Posted August 14, 2015 Share Posted August 14, 2015 Hi Raddys, I've just had my headlights polished a couple of weeks ago and I'm really pleased with the results. I took them to my local car detaling place and he cgarged me £10 a headlight. If you want to do them yourself it might be worth be havin a look on youtube first to see if there's any useful tips on there. Good luck!

a98pmalcolm Posted August 14, 2015 Share Posted August 14, 2015 Use the meguirs headlight refurb kit. Works wonders Quote Link to comment Share on other sites More sharing options...
SupraP-Z Posted August 14, 2015 Share Posted August 14, 2015 G3 compound is what i use to buff them up, works a treat! Depends how yellowed they are - you may want to go down the sanding through the different grits route first and then finish with g3 on a cutting/finishing pad. Alternatively you could take out all the yellow with sanding then laquer over the top which is what i did on my pre-facelift lights - came out like glass Quote Link to comment Share on other sites More sharing options...
cered Posted August 14, 2015 Share Posted August 14, 2015 (edited) Machine polish with medium polish & pads = like new after two quick passes Hand wise I'd use G3/rubbing compound witha bit of water sprayed noto the headlight followed by a finishing polish Edited August 14, 2015 by cered (see edit history) Quote Link to comment Share on other sites More sharing options...
ripped_fear Posted August 14, 2015 Share Posted August 14, 2015 What g3 did you buy as personally I woudnt use the coarse stuff. I would wet and dry starting with a coarse grain up to a superfine. Then use a cutting compound (medium g3 will be fine) to clear them up, with aid of a electric polisher or a pad on a drill. Then polish and wax with some decent quality products providing some good UV protection. I used the above process on my Passats headlights and they still look great over a year on, just starting to discolour on the edges again, but I don't keep her well waxed being a daily driver. If you keep on top off the wax they will hold out well and may only need cutting back again every so often. Quote Link to comment Share on other sites More sharing options...
cered Posted August 14, 2015 Share Posted August 14, 2015 Me? I just bought a tube of Carplan rubbing compound from a moorfactor, pretty good stuff but I wouldn't use it with a machine as it's a bit gritty. Quote Link to comment Share on other sites More sharing options...

rider Posted August 14, 2015 Share Posted August 14, 2015 If you haven't got anything specific to hand and you have a can of Brasso sitting in your cupboard then this is an excellent cutting compound to use on plastic headlights. Followed by a normal polish buff afterwards. Quote Link to comment Share on other sites More sharing options...
Annabella Posted April 16, 2016 Share Posted April 16, 2016 Just done my J-spec pre facelift headlights this evening, not brilliant but damn site better using Colgate, some baking soda and elbow grease, finished with WD-40. Quote Link to comment Share on other sites More sharing options...

You have done a very good job there, get some good layers of a decent wax on them to help protect them. WD40 will not finish them and protect them for any length of time.

stevie_b Posted December 11, 2016 Share Posted December 11, 2016 I recently cleaned my headlights using a Meguirs kit to clean them up, then used this stuff to stop it discolouring in the future: http://www.elitecarcare.co.uk/optimum-opti-lens-advanced-uv-protective-headlight-coating.php It's not cheap (!), but we'll see if it does what it claims to do.
