Maybe I should call this post, "Ugly Scarf Joints, Part 7."
I'm building a Wood Duck 12 hybrid, and the scarf joints on the bottom panels came out a little rougher than I would like. I held each panel a few feet from the scarf and let it bend under its own weight. The curve was fair and I'm confident the joint is strong, but I can feel a hump when I run my hand over it. If I decide to smooth over this hump for cosmetic purposes (which I may or may not do,) any advice on what to use? I was going to use some standard wood putty from the hardware store, but then I started thinking about epoxy and wood flour. But the epoxy route seems like if might be more difficult to sand. I'm basically looking to do what you'd do with Bondo on a wrinkled car fender.
By the way, I'd prefer to fill the very minor dip on the low side of the joint rather than sand down the high side, so as not to remove the outer ply from one side of the joint.
