FWIW...I replaced the headliner in our Tartan with a Masonite type product from Home Depot. Some would say not the best product to use but I figured it was pretty much the same as what was in there and that lasted for almost 30 years. If it gets wet it will have to be replaced, but then I don't have any leaks in the deck. It is covered with a glossy white finish on one side and easy to work with. I used the old ones as a template and I also add some insulation when we replaced it, boat seems a little more cozy now and has a new headliner
