On one side of my Mansfield I am working on, there is some rot and wood loss of the inwale where it meets the fiberglass hull - around the area of where the thwart attached. The rest of the inwale is in decent shape. I assume one option would be to replace the whole thing, another to replace a section.(which is difficult because on the this model there is yet another rail attached to the inside of the inwale - see picture) This inner rail is in great shape, but impossible to remove without damaging - so, I'd like to know if another option would be to use an Epoxy Resin w/Filler mix and just fill in the bad area. If I did this right, would it hold the thwart or yoke when reattached? If so, what kind of filler should I use? or what would you al do in this case?
