The German group got back to me and mentioned there is a huge interest in replacement gaskets but the tooling cost is so high, that they cannot proceed with having any made.
However, I did find a potential alternate product. I found a window gasket at Home Depot and it is very soft, self adhesive, and white. I think this will work so I will see if I can install it today and report back here.
