How do you get Fuchs polished when the anodizing has been "spun" off?

[EarlyPorsche]

I had a really hard finish on one of my Fuchs wheels. To get the anodizing off I had a wheel repair shop sand blast it. Well they also spun the lip using some sort of abrasive and so now it is full of lines. How do I get it so that it is perfectly smooth again and therefore takes a great polish? Do I sand it?

depending on how deep the "lines" are, start with a reasonably fine sandpaper and work your way up until it's really smooth. Then start with the polishing compound. I think I went from 800 up to 1500 wet sanding mine before I polished them. It's a lot of work, but the smoother you get them before polishing the better the end result will be.

Now that you have polished wheels (not anodized), you can (should) use Al/Mg polish and wax them afterwards to help keep them shiny longer. Unprotected alloy will oxidize fairly quickly.

I sanded the very outside outer 1/2" anodized lip (hard stuff to start with) starting with a small electric hand sander (60, 120, 200 grit as I recall), then followed up wet sanding (by hand) with a few more finer grits up to 2000. Then Mother's Aluminum & Mag polish and that technique got every single sand mark out and a perfect polish.
