Anyone have experience with discoloration of the headliner on a 450? I am looking at a 450 and the overhead has a brownish discoloation that looks like the effect you might see from leakage, but it does not appear to be from that, it's not where moisture would collect and is quite widespread. I considered it might be age related, but where its a 99 and I have not seen it on others. I am looking at possibly painting the overhead, but wonder what types of paints would adhere and not try to peel over time. The boat is very clean and smells fresh without and mustiness.
