Tom,
That is the garage floor and the stain was from a spill. My room is much worse than that.
Not sure yet what acoustic treatments in my room survived. Anything on the floor that is not metal or painted is toast, and that was most of the old treatments.

These will go in the smaller room that is dry on the other side of the house. It needs acoustic help and these should be fine with some free standing acoustic absorbers and bass traps.
If I can, will see about the Sonitus USA treatments. Depends on what happens in the room. UGH!!!
