Hi All,
How are original Fuchs finished before they are anodized? Are they glass beaded, or polished?

Thanks,
Tom

The entire wheel is anodized and then the center is painted.

Yes, but before the wheel is anodized, is the wheel blasted or polished, or ?

Read the link to Jack's article. Here is an excerpt with your answer:

From Porsche 911: Forever Young, by Tobias Aichele
"To be precise, the Fuchs wheel was formed by the following steps. A pressed piece of stock was forged to make a forging blank. Next, drop forging the blank produced the ventilation holes and deburred the flange. A further drop forging step resulted in a split flange, before the workpiece was widened by rolling. And here is the secret advantage of this complex manufacturing process: the Fuchs wheel stayed in production for so many years because it could be rolled to any width desired. The forming process resulted in a wheel with a completely finished inner side. The outer, visible side of the wheel was turned on special lathes, which resulted in the smallest possible wheel imbalance. A carefully developed surface finish -- polishing, anodizing, and painting -- permitted different design variations over the years and assured high corrosion resistance."
