Condensation and mildew are problems here in CA too. I have a lot of bulkhead rot damage so I am trying to minimize moisture inside. The thing about the headliner is that it hides minor leaks pretty well. I would rather have the deck fittings in plain sight and make them visually more acceptable by using some shiny and well cut stainless pieces. Sorry for drifting off topic and making this into discussion about the merits of headliners. I will leave this alone to those who would know about the proper pricing for headliner replacement.
