I secured my boat travel cover with a bungee cord that has left marks on the hull exterior. I tried using degreaser and it didn't do anything. The marks are from the plastic exterior of the bungee hook.

The boat hull has a valuable "machine turning" pattern on the exterior that I don't want ruined.
What are the suggestions for cleaning up that ugly mark?
