I was able to clean up spokes w/o changing finish. On the wheel I used JB weld to fill in cracks and put leather wrap on it. I am going to do the same for my 1967 wood grain wheel as the spokes are like new but the plastic wheel is terrible. I will fill in bad areas with epoxy and use silicone/leather wrap This is chrome on spoke and riveted pieces are chrome but looked maybe brushed.
