Just one of those things, it's possible that the owners would just let it slide and chaulk it up to being a renter, but its hard to say. There is a product called Gel Gloss in a bright Fuschia colored can that's used on formica, fiberglass, etc. that might help shine it up some, but that's about all I can suggest. Without seeing exactly how bad the damage is, well you know.
Anyway, talk to the owner, and see what kind of resolution you can come to. Good luck!
