Fred: I scuffed up the petals with sandpaper, sprayed with rattle can silver - here is a pic of the products used - it is just modern german alloy wheel silver I had from touching up my Cayman rims. The silver is very bright (and shiny) The matt clear really tones it down and darkens it a little. I need to get some front wheels soon, and will probably redo these - when I do them again I will do as you have - bead blast down to metal - then I will use 2K epoxy and then 2 stage silver and clear instead of spray can.
The taping is the only real slow part to this - I need to do a better job on getting a clean edge around petals next time.
In various threads I also found guys that used Krilon dull aluminum 1403 or brilliant silver, also Rustoleum Satin black, and Satin clear
