Great for reducing interference with guitar pickups, regaining privacy in a modern world full of rf imaging systems or helping any room in your house LARP as a SCIF. Very easy to roll on and adheres to all the stuff interior/exterior paints do (ply, cementboard, drywall etc). Woremor and Y-Shield are the same paint from the same factory so they can be mixed and matched. Low VOC, low odor. 2 gallons was enough for two coats on a 12x16' room, walls and ceiling.
