The cracking in the gelcoat layer varied from small spider cracks to delamination with fiberglas layers including some areas that had to be completely rebuilt. Some of the cracking was restored by sanding, most of the other areas had to be ground out with a carbide, mostly at corners, and were filled with epoxy fairing compound. That is the green stuff you see in the picture. The corners of the "cab" were really bad and required a great deal of work. New wood reinforcements, biax and cloth, finish smooth with fairing. If you look closely, the small indent line on both sides in the rear are gone, they had long cracks down the middle, and there just isn't a way to fix that. I hope that the cracking is contained and won't return, but I doubt it. I'll finish and enjoy the craft and create memories. I'll post more pics using my camera instead of phone, I can't seem to post pics from this phone.
