An anodizing shop can do a two step process to get the RSR finish. Many are reluctant to do it though. Each shop will have their own solutions and application specific details. It's best to provide an actual example and photos at the very least. After you or a stripping shop strips, preps and polishes the wheel, the anodizer can apply a clear process to the entire wheel for a base protective layer. Many DIY will do all the polishing but not do the anodizing leaving their wheels unprotected. Not good.

This first dip is the final look of the outer rim edges. It is not mirror or chrome looking and should not be. It will be slightly duller than the polished bare wheel. Next tape off this outer-edge to the first radius to keep the clear polished look to the outside edge. Then re-dip (second step) in a more diluted acid solution from the first dip with higher current. This will affect all un-taped/un-masked arears of the wheel to get the frosted or duller or satin look to the inner rim. The petals and centers can now be painted. A satin black is my preference and gives you a Fuchs factory look.
