HELP...Bubble Wrap Marks in PIANO BLACK Speakers??

I just purchased a pair of Piano Black speakers here on Audiogon. I received them today (9/12/06) nicely packed and carefully wrapped with bubble wrap. As I unpacked & unraveled the bubble wrap from each speaker, I noticed the bubble wrap left round shaped dot marks on the Piano Black finish of each speaker. It is not something that can be felt with the finger, so I thought it would wash off easily.

I tried cleaning with water, Windex & Orange BLAST Auto/Shop degreaser. Nothing worked. Then I tried Liquid Glass auto polish and Zymol cleaner wax. Still, I can't remove the bubble wrap markings. I even tried 70% rubbing alcohol in a tiny back corner. That did not work either.

I'm getting a bit nervous now, since these speakers were stored several months in this wrapping and they're all covered with the marks like leopard spots. I don't know if the marks will come out now, or how the Seller will respond to this. He is aware of the marks, but not that I can't get them out. I'd really like to remove the marks and to keep the speakers. Does anyone have suggestions for a cleaner for this?
