Hello guys, just wanted to encourage other convertible drivers who had the same problem with a milky rear window as I did. I ordered one in the bay with zipper principle. Was a bit skeptical, because everyone is writing, it is not possible to make it themselves. I changed my disc today and am absolutely overwhelmed by the result. Already at the second attempt of moving in everything sat in the right place. All promises of the seller were in the instruction I have needed with indentation of the disk and then glue about 2.5 hours with another person. I am really satisfied. So trust you people! Greetings Ingo
