My Demon is back from paint, working on the assembly process. I’m restoring the car mostly stock body/interior wise, but will have a hot small block, and at 51 years old, a little less noise and heat would be nice. I’d like to use some sort of sound deadener under the carpet. There are a lot of them out there, what is everyone using, and what kind of results do you have with it? Tell me the good/bad etc.
