So my car is pretty light right now, and I figured it would be smart to put back the asphalt sound deadening that some idot (me) painstakingly removed from the car during the build.

Any ideas on the appropriate stuff to use? My first thought is dynamat or something similar, since it is intended for the same purpose. I am actually looking forward to this as the car should get quieter and less hot inside with the insulation and carpet back in place. It will be nice when I don't have to run a full tank, spare tire and passenger seat.
