10+ year old polishing compund I used to use on my cars, and a little Mother's Spray on Wax. The scratches still show a little more than they do in that pic, but compared to what they looked like when I first got up it's pretty decent.
I also think I could probably buff them a little more when I have more time...I decided to ride to work so I had to get moving since I like to take the back roads from Ossining, NY to Stamford, CT to avoid I-287 and I-95.
