I have a roll of 1/4" thick neoprene (54" x 9 feet) lying around and was wondering if this could be used in place of ensolite or overkill? Just wondering if anyone has used neoprene and what the results were. The properties seem to be similar.
From what i understand, ensolite helps kill reflections. neoprene is more of a sound blocker/barrier. i think they both have their own usefulness in the car
