I was just wondering if anyone had the Perma Plate package applied when they bought their Z4? I had it done and it seemed to make the car shinier, if there is such a word. Also, on the perma plate website (http://www.permaplate.com I think), it says that no waxing is ever needed. Instead, it says that Perma Plate products should be applied every so often. I wonder if this is just a way for them to get me to continue buying their products?
