Query: WHAT IS THIS STUFF?

I just received my donut pan from Amazon in 4 business days despite having chosen Free Super Saver Shipping. I love Amazon, but my opinion of this pan is so far very unfavorable. It came with a card board label attached to it with some kind of tar-like substance that I have never come across before. I can't even get it off with Goo Gone. The instructions and recipe that is advertised to come with the pan was completely torn off because the sticky stuff was placed exactly on the English version. I am tempted to pack this up and send it back without even making donuts because I don't know how I'm going to get this stuff off the pan. If I figure out a way and use the pan, I will update my review.
