I just split my old GNU (not ready to split one of my Lib's just yet). The cut turned out perfect as did all the holes I had to drill and fill. (I must admit I was a little nervous at first). I bought some of the West Systems G-Flex 650 marine epoxy that DeeJayoh recommended above. It worked perfect. I also used it to seal the sides. Anyhow, wanted to thank everyone for the advice... These threads have made things easier. Now I just have to learn how to skin up the steeps.
