(10-03-2006) After a month, workign on it between other project etc...I am almost done sanding. I just have the "hard to reach" spots. Starting to feel good about this...BUT, my idea of not having to paint/gelcoat the bottom this year has been thrown out the window. The gelcoat is rubbed through to the fiberglass on about 80% of the keel and there are some serious scratches on either side of it.
