I also have problems with my WJ sunroof rattling. Soon I will take that sucker apart and I will let you know how I fix the problem. For the most part the rest of my Jeep sounds pretty decent. I have the entire back end done with Ensolite and BXT II, zero sound coming from back there. I also have an issue with my rear view mirror rattling but ANT from Second skin told me to take it apart and put Damplifier on the surfaces. I will also let you know how this turns out. Nice looking 18"
