How well does fiberglass resin work as a sound deadener? I was told it works well, but im not sure. I was thinking about just pouring it into my trunk lid to stop the license plate rattle. But im not sure if this is a good deadener. What do you guys think? Can you guys tell me of some good deadener's that aren't dynamat or anything like that? Thanks
