This is an image I captured of Mercedes Maybach rim at Chicago Auto Show..More of a polished surface, but Mercedes did mirror polished finish which I feel is a deficiency... This image presents slots that are smooth finished and painted black.I was conidering this black finish with OEM Lexus rims in the visible slot area to provide more of a refined look...or...paint the slot arear as car color...Another suggestion was to polish the OEM rims mirror finish and mix a small amount of paint to tint
