[QUOTE="Rudy, post: 7017063, member: 568035"] The thing to think about when using a sprayed damper or expanding foam on a panel that is visible from the outside is that you are pretty much precluding future repairs to that sheet metal, even something as simple as PDR. I'm currently pulling both things out of a car and I really can't overstate how much I'm regretting having put them in there. The important point about barriers is that you really only need one layer between what you are trying to block and your ears. I'm assuming here that the neoprene you are talking about is very dense and not neoprene foam which wouldn't block much more than expanding foam. Sound doesn't care if it hits the blocker on the interior structure or the inside of the full quarter panel. This works both ways - the barrier will also protect the outer skin from energy from your sound system. [/QUOTE]
