I have started removing what I need to in order to swap out my bulkheads in my O' Day 25. I removed the hanging locker behind the head and the platform that the porta-potti sits on. The vinyl(?) covering on the hull there was falling down due to the water infiltration from around the chain-plates. Hence the bulkhead swap... anyway, what is that material? I cut it with a knife and pulled out that section. Can I get vinyl wallpaper and replace it or is there something specific I should be using there? Or, should I just clean it up, sand it, and paint it?
