Inside the cabin of my recently purchased 1997 38 foot Beneteau, the white wall liner with black foam backing, is pulling away from the wall. The black stuff floats in the air - not healthy to breath. Not pretty either. Does anyone have any ideas on how to repair/replace this lining? The boat is in Florida so humidity could be the cause but we have'nt had a mildew problem as we leave the A/C on while at the dock.
