Puzzle joints aren’t perfect. I think where I erred is I tightened my thumb bolt knobs too tight, should have relied on the weight of the bucket more. I’m trying that on Plank 1 Port and Starboard (stacked). We shall see. I cleaned up drips and puddles with a painters tool and a heat gun. I just lightly sanded the puzzles. I don’t want to burn through the veneer. My plan is to deal with it when I fair the inside and out prior to final epoxy/glass. Probably use epoxy and micro-balloons.
