kyle_winterburn Posted November 23, 2012 Report Share Posted November 23, 2012 Hi guys as titled I am wanting to wet sand my headlight lenses to get rid of a slight yellowing. What grade wet and dry is it recommended to start and finish on for best results. And would any decent cut polish ie t-cut work to finish off?? Or would g200 / g300 etc be better first ?

Devious Posted November 23, 2012 Report Share Posted November 23, 2012 (edited) Sounds mad but the gritty cheap toothpaste. It has a polishing effect and the baking powder really helps to clean them. Check you tube out for videos. Hoohoohoblin has a vid of it. Edited November 23, 2012 by Devious Link to comment Share on other sites More sharing options...
harv_j Posted November 23, 2012 Report Share Posted November 23, 2012 I've heard great reviews about the Meguires Plast-X. Alot of the gen 7 owners use it to restore the headlights. Link to comment Share on other sites More sharing options...
Lex_GTS Posted November 23, 2012 Report Share Posted November 23, 2012 Plast-x would be the best bet. Toothpaste is essentially a very very high grit compound. Link to comment Share on other sites More sharing options...

ashparky Posted November 23, 2012 Report Share Posted November 23, 2012 i wouldnt even bother sanding, i just use a decent medium compound and polish up afterwards, even standard stuff like g3 or t-cut will do just as good job as sanding if you put a bit of elbow grease.

Cravo Posted November 23, 2012 Report Share Posted November 23, 2012 Plast x mate all the way. I got mine looking like glass just with plast x Before After Takes a bit of hard work and elbow grease I spent a good couple of hours doing it but the results are worth it Link to comment Share on other sites More sharing options...
dazzaboy Posted November 23, 2012 Report Share Posted November 23, 2012 i used autoglym paint restorer then proshine polish sometimes called greased lightning worked for me. this is also great for polishing paintwork can use on dirty cars but i don't i always wash and leather first.

Ade2659 Posted November 23, 2012 Report Share Posted November 23, 2012 I had some yellowing on the gen7 headlights and found that using a clay bar got rid of it Link to comment Share on other sites More sharing options...
kyle_winterburn Posted November 24, 2012 Author Report Share Posted November 24, 2012 Thanks guys I had real quick go with the remains of a bottle of safe cut i had. Seemed to improve slightly but light was fading last night so hard to tell. So looks like sanding wont be ness I will just have another with something a bit coarser next ie some g3 from work. May have crack with the machine polisher as well? Link to comment Share on other sites More sharing options...
ashparky Posted November 24, 2012 Report Share Posted November 24, 2012 yeh i did some on a focus with the buffer and it works quite well, just dont go too hard and watch the edges of the paint around Link to comment Share on other sites More sharing options...
splinter Posted November 24, 2012 Report Share Posted November 24, 2012 I tried some 2500grit on a gash set of headlights I had lying around that had some bad yellowing, fucked em up and went opaque. I imagine the next week or so of graft goin higher an higher and then using compounds and then polishes will get there, or you could just use plastiX to begin with!

Monkey Boy 1 Posted November 25, 2012 Report Share Posted November 25, 2012 I'm surprised this has happened on a 6 as they are glass lenses, I've seen it done on 7's before and other more modern cars with plastic lense covers. Are you sure it is not on the inside of the lense where there can be a condensation build up and then you can get a very fine mould build up.

Monkey Boy 1 Posted November 25, 2012 Report Share Posted November 25, 2012 Ah, I see. As the other guys have mentioned, toothpaste works well. Take your time and it will clean out. As with all things like this, try it on an inconspicuous area first as not to cock up a complete headlight Link to comment Share on other sites More sharing options...
Sawyer Posted November 26, 2012 Report Share Posted November 26, 2012 If your going to wet sand them, you need a machine polisher and compound to get them back to being clear again, but they will look "mint". Unless you've got arms like popeye on roids. Link to comment Share on other sites More sharing options...
Xanadu Posted December 1, 2012 Report Share Posted December 1, 2012 (edited) P2000 paper, followed with liquid Brasso. I removed the Toyota logo from the black plastic bonnet grille on my Gen' 5, so it should work just as well on your lights. Find an old worn CD case and practice the technique first to see if you're happy with the finished result.
