So, no one seems to have answered the question.
Are the mat finished areas between the paddles just sandblasted or painted?
I will add that to take off the existing anodized finish just use yellow easy off with lye...a few coats finishes off the anodized layer, then you must use borax straight to get rid of any discoloration.

I thought I answered the question but...
The 914 fuchs were NOT painted from the factory. The paddles were lightly polished almost a brushed finish. The "background" (area between the paddles) was left rough, maybe sandblasted (IDK) and the whole thing annodized. So the paddles and rim and the background are all annodized. IMHO You can not replicate the finish satifactorly by sandblasting the background.
Annodized aluminum is tough. I consider chemical etiching to get it off pretty agressive. You can remove it by agressively sanding and blasting too. But why? I don't understand why you would want to to try and remove the annodized finish and make the wheel look stock. Once you remove it your maintenance on the wheel goes up. If you must paint I would suggest painting over the annodization which too will increase maintence to keep it looking good.
The only reason I would recommend removing the annodization is if you want to polish the wheels. The tutorial I mentioned uses EZ-Off (lye) to remove the annodized surface. Polished wheels have a bit more maintence, but if you keep that high luster they are not bad. There are alot of products on the market to keep them looking shiney too.
