Headlight Lens Restoration Using 3M Restoration Kit

I completed the clear light mod on my car a number of months back. When completing this mod I noticed the headlight lenses were not in the best condition, and it is something that has bothered me ever since. Here are a couple of pictures of my offside headlight showing the oxidation and damage to the lens -

As you can see this lens was pretty scruffy. It is hard to capture the scratch, but trust me it looked pretty bad in real life! The near side lens was better, but again it had marks and oxidation that let the look of the car down.

I did some research on how to restore the lenses, and it was then I discovered the 3M headlight lens restoration kit -

I found some reviews on this kit which were very positive. Basically the kit comes with a drill attachment and 3 different grades of sanding disc, a polishing disc and some polishing compound. You use the attachments with a standard drill to sand and polish the headlight.

I am a complete novice when it comes to this sort of thing. I have never used a machine polisher before and I have never used wet and dry to restore paint etc. Although I was nervous in using this kit I decided to take the plunge as the headlight lenses were really letting the front of the car down.

I ordered the kit, as well as some protective tape direct from 3m. This lot came to about £28 including delivery (I ordered loads of tape though as I would use this in the future). I also ordered a water spray bottle as you need to spray water on the lens during stage 3 (about £3 from ebay). This bits arrived a couple of weeks ago and today I got round to using it.

Here is a picture of all the bits. I have labelled what discs are used at the different stages (the drill attachment is hiding behind the stage one disc). You get 5 stage 1 discs, 4 stage 2 discs, 1 stage 3 disc and 1 polishing pad.

I gave the headlights a quick clean and then taped up the headlights. This picture shows the offside lens taped up ready to go -

I then attached the disc holder to my drill and started with the stage one pad. I was really nervous about doing this as I was worried about messing up the headlight. I made a few passes with the stage one disc. I applied enough pressure to compress the sponge on the drill attachment by around 50% (you'll understand what I mean if you give this a go!). After a few passes the headlight looked like this -

I then moved onto the stage two pad and after a few more passes it looked like this

It is hard to tell from these pictures but the scratches at this point were much finer. I then ran a few passes with the stage 3 pad, this time spraying the lens and pad with water as recommended on the instructions. This is what it looked like after a few more passes.

As you can see you get a bit of frothing at this stage. After a wipe with a cloth the lens looked like this

As you can see at this stage the lens still looks a bit cloudy. At this point I had a close look at the lens to check for any areas that still had scratches or oxidation etc. I then repeated a few passes with the stage 2 and stage 3 pads until I was happy the marks had been removed (please note some deep stone chips will probably still remain, you don't want to take too much out of the lens).

Once I was happy I then used the stage 4 pad to polish the lens and complete the restoration. When you polish the lens you will probably notice the odd mark here and there. I repeated stages 2, 3 and 4 until I was happy that all the marks had been removed. I then completed the near side headlight in the same way.

Here are some pictures showing how the lenses look now -

I was really impressed with the results I achieved with this kit. The nasty scratch and oxidation has been completely removed. Some of the deep stone chips remain, but the appearance of these has been greatly improved. Sure a professional detailer will be able to achieve a better result, but when you consider this is a £20 kit used with a standard drill the results are excellent. As stated before I am a complete novice and I was really nervous about taking this on, however it is a really straight forward process.

It is amazing how the head lights can make the front of a car look tired and scruffy. I was really surprised to see how much fresher the front of the car now looks, the front end has really been transformed. I am really pleased I took this on, what a difference an hour and £20 can make!
 
I am in where did you get the kit from, mine look the same as yours befor. Just bought a DA so looking good. :)
 
Nice one :thumbsup:

They look great now! Its surprising how much difference mint lenses both front and rear make to your car, when I machined my car i went over my lights and it really brought them up and gave the car a really refreshed look.
 
:thumbsup: looks great, what an improvement. i was thinking of somthing along the same lines when i do my angel eye conversion. Do you have a link to where you bought the kit from?

I ordered the kit direct from 3M (http://www.3mselect.co.uk). If you go to shop by category/car refinishing/car car products it is in there. However you can also pick it up on Ebay and other stores.

hi. do you have to seal the lenses after polishing to stop them discolouring again. looking good :thumbsup:

I used some plastic polish afterwards which I am hoping will seal the finish. I will also give them a coat of wax to try and protect them over the winter months!
 
great how to, thanks i will be doing this to mine!. 3M out of stock at the moment. I also notice your shut lines are better than mine on the hood and the lights i seem to have larger gaps which have come from the factory (as I have had from new no crashes or anything)

Thanks :). There should be some play in the wings/front bumper to be able to straighten up your shut lines. If you loosen the bolts at the top of the bumper/wings you should be able to jiggle them around a bit. I had to do this to my previous E46 as they were a bit off and this method worked fine :).

Wow... that's a fantastic job - will look into this too.

PS - Nice tractor! ;)

Thanks again. I didn't notice the tractor reflection when taking the photos!
 
I gave mine a quick go today with Meguiars Scratch-X. Seemed to give good results so far. Must give it another go though.
 
I'm going to give mine the good old toothpaste treatment, seen as its free and my lenses aren't that bad anyway.

I did try some scratch-x to remove to scuff and the oxidation but it didn't make the slightest bit of difference?

I probably didn't try hard enough, or maybe your lights were in better condition than mine to start with?
 
Well I was going to get a 3M kit but having spotted the toothpaste suggestion I gave it a go on my foggy headlamps, ten minutes with Colgate on a small sponge, quick clay bar then bodywork polish and voilà no plaque and with minty fresh breath, nice one :thumbsup:

Visibly cleaner having started the left hand side with the toothpaste,

Finished, well impressed and cost a few pence!

Brasso works surprisingly well too. Tried it on my MR2 rear lights in the past and it seemed to do quite a good job. Toothpaste sounds like a good idea though, might try that too.
 
Autosol metal polish and a bit of elbow grease sorted mine out a treat, and mine were much worse that the OP.

I used this too along with one of those not scratch kitchen scouring pads

So what's the method with the toothpaste? I'm intrigued :)

Put some white traditional toothpaste on a small damp sponge and polish it around in small circles. Most toothpaste contains kaolin 'fine china' clay as a mild abrasive (kaolin is also found in some auto paintwork clay bars). I was amazed it worked so well as my lights were pretty foggy :thumbsup:
