I'm about to add backing plates myself. G10 was recommended and it certainly makes sense but I was thinking about hardwood oak for convenience and cost. Home depot sells 0.5"x6"x4' for $13 that would make several plates. Also in my boat many of these backing plates would be visible and stained oak would blend in nicely.
How much advantage is there to epoxying to the hull? I don't like permanently attaching anything and second, I think I have an interior liner that would make this less useful?
