Ok. Which one of you has even the slightest idea of where a guy can snag some fiberglass tongue and groove panels? I checked the local hardware stores, box stores, McMaster-Carr, googled, oggled... There must be some source for the average home DIYer to lay hands on sheets of this stuff. I thought for sure somebody would have a tub surround kit that had a T&G pattern. Nope.
Free beer for the first confirmed source!!!!
