That peel and stick was being discussed a lot when I did my car. I went to Home Depot to get some, no luck, they told me it isn't in their Canadian stores. I had to get the Dynamat. Only problem I had with the sound deadening was if I had to remove a screw out of the floor such as a seat screw of a stick shift molding screw the black goo caught the carpet threads and started to unwind the carpet.
