After removing the panels and headliner trim around the companionway, I discovered that mice or chipmunks had found their way into the only hiding place left in the boat. One photo shows what is left of the foam backed carpet headliner that was once where the holes in the headliner are today. The best part was the constant shower of mouse poop falling from ceiling. I wasn’t sure about removing the headliner until now but it has to go. Besides the smell it has begun to disintegrate (powder) when brushed.
I would like to replace it with something similar even though it will need to be sewn. I have read that many people just paint in a tan bedliner which may be the best “practical” solution long term and it would be much more economical.
