The manual says: Avoid
: gooping epoxy on the wire holes - it makes it harder to remove them later.
: These wires are like magnets for my shaky hands. I'm sure I sealed some of
: them :-)

I wouldn't worr too much about the wires. I took all mine out by heating them with a soldering iron, and a woodburning tool will work as well. My wires were buried with the inner seams and I just cut one wire near the boat surface on the outside, heated the other side and wiggled it until I could see it move on the other side and then just grabbed it with the pliers and pulled it out. They come right out as the epoxy will soften with the heat. Then when I did the outside seams there were no obstructions.
