The only way to get the trims shiny once more, is to remove the protective lacquer, then polish the raw aluminium to a bright finish.

The problem is once the lacquer's removed, you'll have to keep on top of your polishing. It may however be possible to purchase clear vinyl, and cover the fresh aluminium, protecting it from the elements. (Audi use it on lower areas of the rear wheel arches on certain models vulnerable to stone / grit chipping).

Hi.

Got the same issue on mine 2... I did the metall polish and it looks great for a while then its back to the polish again..

Since black wont match a silver car i'm woundering about Gun Metall grey.. Maybe someone with good skills could do Photoshop of Silver A8/S8 from the side with gun metall grey trims?

Hm...Would 3M Carbon on all that trim be to much F&F ?

I'm just wondering if a rub on 'gun blue' from your local armoury would work, just a thought...

Resurrecting this old thread, has anyone done this and how easy is it to remove/refix the trim under the headlight?
The "chrome" trim under my offside headlight is looking decidedly "milky" so I'm thinking of having a go, but haven't a clue how it's held in place.

You will need to remove front bumper, but you don't have to remove it completely from car just to remove the bit under headlight. You need to undo two big bolts which hold bumper in place and then pry off bumper forward from one side of the car to create just enough space to access from inner side of it to remove some screws with a ratchet or small screwdriver and then unclip the chrome strip. Clips can snap off, so I'd suggest to purchase some clips from Audi or from A8 Parts before removing that strip.

I have powder painted those trims about year ago and I'm very happy with result: http://forum.a8parts.co.uk/showthread.php?t=4587

I have just removed and polished the anodised trim below the boot lid where it sits on top of the rear bumper as the holding clips at one end were allowing it to spring up and damage the lid and the trim. The trim was pitted and worn and so i took the approach that I couldnt make it any worse by taking some wet'n'dry to it. I used 800/1500/2500 and 3000 grade to get a reasonably shiny finish but it is hard work and not all the pits/marks came out. I then spreayed with laquer but, to be frank, havent any great hope that it will last anylength of time. time will tell.

Thread resurrection...


The rear quarterlight window trim on the A8 is well known for going milky, mine was bad, so bad it looked white with the odd mottled bit of aluminium shining through and has been like this since I bought the car. I suspect someone has washed the car with neat TFR at some point in time and left it on too long which caused the damage. I had made several attempts to clean it but to no avail, a search on the net reveals there are two options. 1. Strip off the anodising with over cleaner or caustic soda and polish to a bright shine with Autosol (or similar). The only problem with this is the alloy is now open to the environment and will quickly turn black, therefore re-polishing on a regular basis would be necessary, you could apparently give it a coat of lacquer but if the water got into it again it would look worse than it does milky. Then there is option 2. Buy new trim, but only go down this route if you have a lottery win and are prepared to spend a lot of your blood sweat and tears removing and refitting as it's a pig of a job.

I decided to try and remove some of the marks by polishing with my usual National Products 'A Grade Polish' which I've happily been using for more than 16 years now (details & website here) you can buy it on eBay for £7.50 for a 750ml bottle (LINK HERE)

I started by masking the paintwork and rubber seals (A grade polish should not mark your rubber bits as it contains no powder) then with a microfibre cloth I stood rubbing and rubbing and rubbing for a couple of hours (I need to get a life) The end results have not removed all the marks but it is a massive improvement on what it started off as.

Sadly no before pictures but you can just about make out in this picture how bad the trim was



I might give it another go and try to get a better finish, but this is the end results after hours of work.
