From my brief experience, I have this to offer. Don't pull either the hull or deck off until it has at least one layer of glass on it. I had a really nice looking deck and went to pull it off the form to glass it, only to have the thing shatter into about 6 pieces. The more I tried to move it, the more it broke. Eventually I got it off the forms and then stomped the thing into kindling. Deck #2 isn't as decorative because I didn't have the wood to do it but I glassed it on the forms and had no problems. Just want to prevent this type of frustration to anyone else. It really sucked. Paul
