Goof,
I'd bet dollars to doughnuts that this coverstock is Super-Flex. Sand it 2000 grit first; then use a polish with abrasive in it, like Storm's Diamond Polish. With your high revs you need to make it less grabby and SF is still a strong coverstock, no matter how mild the core is.
If that isn't mild enough, take it to 4000 grit (abralon pad); then add polish.
Still there's only so much dry a Super-Flex cover can be used upon ... Then you'll need a pearl urethane or plastic.
