    Smile Headlight Restoration (With Pics)

    Evening all, Oh how time flys when your working on your car! done a few clean up jobs today interior etc, next minute, got a friend popping over offering me a headlight restoration kit for free... so obviously i didnt refuse!
    Now, ive only done one pass on each light so far, so they are not perfect by any means of the word but they are massively improved from how they were, heres the story:

    Before:



    First job.. mask the area, I didnt have any masking tape and its too late and shops are shut! Improvise! low tack sticky lables!



    First pass with the sand paper 800grit through 2000 grit.



    After the plast X compound and a bit of a buff:







    I didnt take a close before picture of here, but it was really badly damaged with deep scratches and what i can only discribe as a bubbling effect. But after the buff:



    And finaly the passenger side light after (it was originaly just as bad as the drivers side):



    Thanks for looking. Ill update when i do a better job at the weekend.

    You beat me to it. I have the Plast-RX stuff and it works well but my head lamps are in a really bad way. I bagged a brand new head lamp unit (minus the xenon wiring) off ebay for £100. So I will swap that out tomorrow.

    For the other side I got a halogen one from a breakers and will do the old heat gun or baking trick to swap in the internals.

    The problem I have is that the adjusters are knackered on my lamps as well as the lenses being shagged so I need new units

    This is how bad mine are.

    I did this a while back and been meaning to do a seperate thread and bung t in the stikies so seeing as this has been started I may as well do it here...

    After reading several tutorials and write ups on refurbishing plastic headlights most of which involve using wet and dry sandpaper first followed by a machine polish... sounded easy enough but sanding the headlight with wet and dry scares the life out of me but tonight I decided to give it a go...

    Here's the kit I used...


    As you can see from this pic the headlight is fairly rough...


    ...still a bit worried about sanding the whole light so tried it on a small patch in the corner... used 2000 w&d with water of course then went over twice with Menz final finish which resulted in...


    ...happy with that I proceeded to mask up around the light and sanded the whole light face with 2000 w&d...


    ...ended up looking like this...


    ...dried off the water and finished up doing 3 passes with a soft pad an Menz final finish..


    ...the result of the first pass...


    ...and the final result...


    ...compared to the passenger side that I haven't done yet...


    ...and finally a comparison with the headlights on...

    Before....


    After...


    The result of 3 more passes over with Menz final finish and a spot pad on a Kestral DA...


    Looking at this one compared to the passenger side one I decided I couldn't wait and cracked on with sorting that one out too... feeling more confident of my abilities now I went straight in with 1000 grit wet and dry which took a bit of work to get an even finish then worked the light over with 2000 grit wet and dry as before....

    This is the point where you would justifiably feel sick as a pig looking at the very opaque headlight.... Just to reassure you I taped up half the light and did a single pass with the DA...


    ...as you can see its pretty easy to get the finish back but use a hardish pad as my medium pad had got saturated and ended up using a soft pad which took god knows how many passes until I was happy...

    Reminder of the light before..


    ..and after...


    Next thing to do is to get some the Lamin-x film to protect the headlights now the UV layer has been removed and to help protect against stone chips...

    A worth while job to do considering these headlamps are something close to £500 each from a dealer to replace..

    Only thing I still need to do is recoat them either with lacquer or lamin-x film... this process removes the protective UV coating and makes it easier to scratch the headlights etc... mine have gone a little dull since doing it I think but I do go over them again when I do my winter and spring detail... it works on the rear light too by the way

    Looking good mate, nice and clear... Weird, I was going to update my thread with this exact procedure last night to but ended up pissing about trying to get my sig pic up lol. I did it before i put the lamin-x on as mine where rank and yellowed. Took a good hour and about 6 passes on each lense. I used the 3m kit wich comes with cutting paste, drill attachment and 3 different grades of pads. Good for the money the kit came in at £23

    Like tufty said, scared the bejesus out of me, after the first pass a actually thought if killed em. Major ass clench lol

    Haha, I would have been worried at first but tufftys thread got rid of that worry! I'm going to do another 5 or 6 passes on each lens this weekend as there are still some noticeable scratches in the corners. Bit or advice xD do it in the day light, halogen lights in the garage doesn't let you see the things that day light does!

    can anyone tell me were i can buy the products from.... as a while back some scumbag poured paint stripper on my bonnet and rest of the car managed to get it off before to much damage happened but couldnt save passenger light so i think this method would bring it back and be cheaper than a replacement and also may try it on my back light that took the stripper as well
    brilliant job guys :D

    The amount of compound you get in the bottle would last to do about 10 sets of head lights to be honest, the sanding paper wouldnt last that long though tbh! Im itching to do another few passes now, just got to wait for the morning I guess!

    Done this today to my lights using the Meguiar's kit the result is good but could be better can I start again and sand them again or not?
    I was using a rubbish cordless drill I'm not sure if that's the cause or not enough sanding the light felt nice and smooth after sanding.

    Great improvement and a cracking job,i did my brother transit with various grades of wet and dry then buffed with G10 compound.Didn't look as good as those though.
    well done and thanks for sharing.

    Further to this, I recently redid mine as obviously I had rubbed off the UV protection and the lights had started to go a little yellow again...

    ...this time however I bought some Lamin-x to act as a UV shield... also had some LED sidelights from Trups to fit...


    ...after a couple of passes with the DA...


    Applying the Lamin-x..


    ...and done ready for trimming...


    Refitted..


    ...and next the passenger side


    LED sidelights...


    ...old 'blue' bulbs...


    After the success with the headlights I had a go at the foglights too... I have read up on some techniques for this as they are glass but I don't have a coarse enough cutting compound to give it a go at the moment so decided just to do a few passes with the coarsest compound I had and while still showing signs of pitting they were a lot clearer so applied a little lamin-x over them too...

    Before...


    ...after...

    I keep meaning to brave this but... worried i will make it worse rather than better.
    To be honest mine are marked on the inside a little too so never going to be A1 as im guessing splitting the light isnt a goer?
    The outside of mine became damaged when i went on a track day about 4 years back... the marshal said i have to put tape on my lights... i told him they were plastic not glass but... he insisted, when i came home i noticed that there was a noticable mark on the lense where this tape had been. It wouldnt come off with polish alone so... will probably need wet and dry .

    I ask questions because i change my mind so much. If i ask questions you have already covered... just leave it be?

    1000 grit then 2000 grit with a circular motion using warm soapy water does the job... I used Menzerna RD 3.02 to get rid of the haze with a medium pad then used 3M ultrafina with a finishing pad to get the gloss back... needed several passes but use a da as a rotary may well generate too much heat and burn the plastic... Lamin-x has UV protection built in so will prevent them discolouring and obvs give stone chip protection...

    Only got my S3 last weekend but the cloudy lights were bugging me, so I restored them. Here are my results. I got some Megs sandpaper and finished off the process using the 3M system. It's not far off perfect. Perhaps some more sanding would've done well but it's a hell of a lot better than before. Let me know what you think! Also reading the comments above it appears I should fit some laminex to protect them from the current bun!

    Essential items that I had to buy:



    Before:



    Masked off ready for sanding:



    Sanded Down:





    Polished and complete:







    Much better!

    Hi Lads, strange how I havnt stumbled accross this thread before and yet ive been having exactly this problem with my S3 headlight lens, and have a thread (well kind of taken over an old one :/ ) on another part of ASN.

    Now save save repeating threads and posting things twice on different parts, which I know pisses people off, here is the link to the thread that ive been posting my troubles: Audi S3 Headlight Lens?

    Unlike you guys who seem to have achieved a very good end result, I went through the process and it didnt really come out much different.

    Now im not asking you to take hours out of your day to trawl through someone elses problem, but perhaps you could drop me a PM with your email on or something and ill send you a revised extract out of the link (above) which I will sum up my problem and the advice I need.

    Your help and guidance would be greatly appreciated

    Anton
