Hi Matt. Sorry for lack of detail. I sealed up the last of the raft and blew it up, but it lost air. One problem spot was the very rear-most point where the flap hadn’t stuck down well with the sealant. I used rubber cement (HB-66) that I’d used to attach the tie-downs to add a small section of inner tube patch over that. It didn’t work well, so I eventually super-glued it. I also had some leakage from the inside ends of the seam strips, and I added some sealant to those pockets. I also have a few points where I touched the fabric with the iron and I understand that this can leak to leakage. I’m a little concerned that I’ve completely ruined it, to be honest!
