Still at it. I have 6 areas approx, 2 feet by 2 feet opened up. The end grain balsa is in and two layers of woven mat is vacuumed bag under them. I hope to wrap that work up before the big freeze. I will restore the inner layer in the spring. I have learned a lot about fiberglassing upside down. The repair work is great. The sponginess up top has gone and it feels solid to walk on. I am glad the boat will get a new lease on life.
