The only products I use on my car and customers cars... So easy to put on and take off. No powdery residue, and smells great. If you are looking for top notch, get it. I have used Crystal Rock and Shield and love them both. CR looks phenomenal and Shield works great for DD and looks great also. Have not had the chance to use Blau/Weiss though... Have to pick some up and try it.
