I bought an old Tanzer 22. Last spring I replaced the cockpit core plywood that had rotted.
MAS Epoxy was great to work with. I used various speed hardener.
3 Years ago I also built a stitch and glue Chesapeake Light Craft Skerry, a 14 feet sailing dinghy. I used MAS for the project and have only good things to say about MAS Epoxy.
