Back in the early spring (May) when I first tested out the boat, I made the spruce pitch according to the temperatures of the time. The ideal ratio of tree gum to fat in the pitch is dependent ambient temperature of the season. Too little fat and the pitch will crack and chip off in colder weather, too much fat and the gum will become runny during hotter days. Well, I must've put in a tad too much fat, because after resting the canoe on horses in the protected confines of the garage, I awoke to the horror of messy, melted, runny pitch leaking down the side of the canoe. The stern in particular took the brunt of the ugliness, as I had loaded up on this weakpoint where most of the leaks seemed to have originated.
Runny pitch down the sides; Lots of runny gum on the stern
I guess the short term solution is to sit the canoe right side up on some slings and hope the gum runs back down to the seams. Either way, my ugly duckling of a canoe now looks like she's got runny mascara.
