I am certainly no expert, but it looks to me like industrial grade (rather
than body shop) fiberglass mat; as used for molding large items from
fiberglass (like hot tubs).
It also looks to be somewhat separated, from long storage. As I understand
it, if it has also gotten damp, it may be useless now. Fiberglass mat tends
to hold water, which interferes with the resin bonding properly to the mat.
Or so I've been told, anyway.
