I wanted to restore a scratched emblem for my 1969 R50US. First I purchased some glass polish and some small buffing wheels. I was able to polish out the scratches but when I finished I had also polished all of the patina. I was able to chemically age the nickel a little to make it look it's age but I still noticed that there was some copper showing. I had a home plating kit from another project so I touched up the spot where the copper was showing. attached are some photos. I next want to try repairing another one that has chipped glass. Attached are some photos of the progress.
