Things Go Better With Coke, smaller version sign

Picked up this sign locally at the end of the year. It was advertised locally at what I feel was average retail for a good shape version of this sign. I was silently keeping an eye on it when the seller cut his price in half and that's when I contacted him and said I would give him what he wanted.

When I looked at it in person it was in real nice shape but there was a thin, grimy layer of residue on it that I was sure would come off but not positive. I first washed it with soap and water and it did nothing. Then I went to the compound. Signs of this period have proved to have good paint on them so I have kind of learned the limitations of rubbing on them. It took a good solid day off and on polishing by hand to get it done. The pics show the middle progress. Small but huge difference.
