It's a little hard to see, but I actually broke the stringer. The deck of the board remained intact, but the bottom was severly cracked exposing the blank and as I indicated above the stringer was broken.
If this were a more minor repair without any delamination or structural damage some epoxy with microballoons would, no doubt, have been sufficient. I wanted to add some structural integrity to ensure I didn't snap the nose off in use.
I opted to epoxy a e-glass fiberglass patch over the offending area.
The first step is to prepare the area. Much like body work, I carefully pulled the dented out as close as possible to it's original shape. Including twisting the nose back into alignment. Then I sanded the entire area to give the epoxy and patch a good grip. Finally wiping the surface down with a tack rag to remove any dust. It's not a good picture, but the prepped board.
