Something just came to mind...
My fiber glass gunwales.
On my used project boat there are some things installed already on the gunwales. The rod holders are flopping loose, the cleats aren't very secure either. There are some existing holes I need to patch. The rails seem secure at the bow.
I'm planning on relocating the cleats and rod holders. I don't want to just secure them into the fiberglass. What I was wondering...? Would I be better off installing aluminum supports under the gunwale or just go with wood? If wood, what is the best way to water proof it? Non-pressure treated I'm assuming and then poly resin?
