I just removed a shitload of that crap. Some kind of white fabric perforated nagahide with acoustic holes, and completely disintegrated black foam. It makes me worried that it may have lead in it, I've heard sounddown had lead or something for sound deadening. I replaced it with those foam egg crate material. It's probably supposed to be fire retardant, and I'm not sure. Maybe I'll try setting some on fire. Outside of the boat that is.
