Matt,
Well, you have said that the boat should hold air overnight. I am finding that once I temper up the boat, it loses that nice pressure within about 10 minutes, and overnight sags noticeably.
I found (or maybe created?) some more spots today by painting it with the soap and then taking it in a hot shower. As the air expanded I saw some additional leaks, and I have now sealed the line where the floor meats the raft at the front of the boat all the way around, maybe the front 1/3 and where the front two joints meet. The aquaseal is drying so I will report back after it tries and I try again.
p.s. folks get yourself a respirator, they are $15 dollars and are necessary when dealing with this solvent. I can feel the effects of using it without protection and have ordered a mask.
