I completed gluing my puzzle joints on my Shearwater 17. It has cured for about 60 hours and looks pretty good. There are a few small areas that could have used a bit more epoxy on the glass strip but the joints are well covered. I had some epoy leak underneath the joints leaving a film and some epoxy slag on the outside panels of the boat. Do I need to sand that off using a scraper or sandpaper now or wait until I get thge boat togeather for more support. I don't want to break a panel or damage it being to agressive. Thanks !
