Pre-planning is the most sensible way to work the glass and resin. Sticky latex gloves and scissors don't mix well. Sticky gloves and rolls of glass don't mix well either. At this point, I had pre-fitted all of the wood parts, and was satisfied with the fit. A lot of time and effort went into that. Some of the small pieces at the rear were so rotten, I could hardly tell the dimensions and how they fit back together. Note the 1" portable strap holding the sides. Prep work is the ABSOLUTE KEY. Why invest all of the time and money to do a lousy prep job? Polyester resin is easy enough to work with, but it requires a CLEAN, SCUFFED, surface to bond to for the initial bond. The 1st bond is purely mechanical. Since the skeletal replacement is not a true laminination process, CLEAN, and SCUFFED is the only suitable choice. I used a 34 grit flapper wheel on my mini-grinder, and ground 4" back from all old bonds. Both sides of the stringers were ground, as well as both sides of the transom.Wipe all surfaces to be glassed with acetone.
