Does anyone know if Rimowa still sells the Polish & Repair Paste?

With the exception of a seller on Amazon that is charging over $50 for it, I can't seem to find anyone in the US that sells it. I also happened to check at the Rimowa store at a large Asian airpot last week and they didn't have it either.

Has the new Rimowa stopped selling this product? If so, does anyone have any recommendations for cleaning a glossy Rimowa suitcase? I have some gunk and a ton of light scratching on mine that I am hoping to make less noticeable.

Thanks!
