Right lads, a DIY alloy burnish was on the cards today :L - wheel was looking typically tired and had seen better days but instead of painting & lacquer I decided to leave the finish as a polished metal - I just hope the finish lasts - time will tell I suppose! cheers :beer:

Thanks for all the comments :L They are my old mans wheels not mine

Sean - All surface blemishes were completely removed. The 60 grit sheets also took out stone chips that had gone through to the metal!

Heres a quick step by step

Basically what you are doing is fully removing the lacquer from the wheel and polishing the metal alloy underneath. As everyone knows the Ford ST wheels suffer horribly from oxidisation causing the wheels to look like Pic 1 above. e The lacquer layer perforates due to kerbing, stone chips and exposes the metal, moisture gets in, gets trapped and its prolonged contact with the metal causes it to react.
Personally believe this to be a combination of poor quality lacquer / its thinness and the poor adhesion to the metal surface

Anyway heres what i used:

Sheet sander (with 60 , 120, 240 and 400 grit sheets)
Detail sander (with the same sheets as above, Ā£13 from B&Q, you will need this if your are attempting to sand with the tyre on as the larger sheet sander cant get to the rim of the alloy
Sandpaper ā€“ 600 ā€“ 800w&d ā€“ 1500w&d ā€“ 2000w&d ā€“ 2500w&d ā€“ 3000w&d
Machine polisher with a cutting, polishing and finishing polish & pads and a wax

I suppose most of the the sanding steps are self explanatory working from the lower grit upwards..

1 - Use the 60 grit or similar with the machine to remove the existing lacquer ā€“ you will know when you have reached the metal as the finish will look something like Pic3 - this took me about 1.5hrs

2 - Work your way through the machine grits over the whole of the wheel finishing with a 400 ā€“ you will notice the larger marks left with the 60grit will get smaller and smaller and the metal will appear smoother.

3 - Now with the manual sanding ā€“ Starting at about 600grit you want to be spending about 1minute per spoke sanding in long strokes over the whole of the wheel. Ater this inspect your work closely to make sure all the larger scratches made by the lower grits are removed.

4 - Wet & Dry sanding next, using a spray bottle with water / washing up liquid as a lubricant ā€“ repeat step 3 for each grade paper.
During W&D sanding you will notice a black residue appearing as you sand ā€“ I believe this is the aliminium (hydrated alumina) with color due to oxidized alloying elements for all you Chemical Engineers out there?

5 ā€“ When you are sure you have gone over the whole wheel ā€“ hose the wheel down and check for scratch marks left by smaller grits. There will be some so go back and wet sand what you have missed, stepping down to a lower grit paper if neccessary and then back to 3000.

At this stage the whee looks OK, a lot better than the wheel before you started but just a little dull. This is where the machine polisher comes into its own. You will need a cutting pad and cutting polish for the initial pass. I used the Menzerna cutting pad & power gloss. This is a heavy combination and will remove the very fine marks left on the metal.

6 ā€“ Heavy Cut Polish - Use the cutting pad & polish on the wheel. (The black residue as mentioned above will appear like crazy ā€“ and will completely turn your pad black but dont worry- this is a good thing as it shows your are working the metal) do this a few times and remove remove the black residue with tissue paper ( I found this worked much better than a microfibre)

7 - Medium Cut Polish - Use a Polishing pad & polish (I used Lake Country orange pad with Meguiars #83) apply the same procedure as above ā€“ Do 2 passes with this combination and then move to the finishing pad & polish combination (Light Cut). This it where you start to see the results.

8 ā€“ Wax

9 ā€“ Go to the fridge and pull out a can of beer

All together it look me 5hrs to do one wheel

Iā€™m not sure how these wheels will end up looking after a few months. Iā€™m guessing they will need looking after in terms of applying a wax to them regulary.

How about a lacquer final coat? Well, if Ford cant occomplish a durable finish they I definately wont be able too. As the wheel stands now, the surface is far to smooth for there to be any suficient adhesion to a coat of laquer. Last night I sprayed one of the spokes with lacquer as a test ā€“ I applied 3 coats and left it to dry over night. This morning it came off with my finger nail.

Ill keep an eye on the wheels over the next few months and report back my findings.

cheers :L

well i did my wheel to mirror finish laquered it about 10 or more times, flatted it then polished the laquer its still fine.its everybodys opinion but i think if i have a choice of keeping the finish intact or nothing at all.Its got to be some kind of protection because its opened to the weather unless your out polishing the wheel all the time,all i do is wash it thats it like i do any other time

We will have to see, if it means using the machine polisher on them one every 6 months then so be it. I dont think the amountof layers you spray on would make any difference because the weak link is the first layer and it did literally come off with my finger nail when I tested it.

We should both report back with pictures every month or so as a comparison

Thats a cracking job mate, 5hrs may seem a long time but i bet when you saw that finish it was more than worth the wait!!

I have just posted about wheels in the car care section as i heard an interesting story this weekend about VW....have a read.
