Price isnt a factor here. i want to know the best sound deadening material. also which is better, dynamat or fatmat? and, anybody had any experience with rattle trap? if so, how does it compare to dynamat and fatmat? are there any other brands out there that are better? i heard someone talk about a jbl product which claims to reduce the noise by 10 decibils or something. not really sure. just wondering what the best out there is.
any posts with exerience/advice about any sound deadening product are welcome :D
