ltk114,
I would be interested to give it a try if you really have given up on it. I live in Montana but get down to AZ (Grand Canyon) a couple times a year – no plans to get back there till late September. The seam in your photo looks like it needs a lot more heat. If that is the only type of error made then it might be repairable with some effort. If all the seams are like that then maybe just do them all again with more heat. If the welds of the tube sections to the floor are like that then maybe the raft would have to be turned inside out somehow. Or, maybe cut the seams at the center of the joint to reseal the floor welds and then re-do the outer seams with wider seam strips (that can cause wrinkling if the strips are too wide. Did you check your Black Baron temperature with an oven or meat thermometer? Mine was set too low (375F) out of the box. There are directions here on the forum of how to increase the heat for the Black Baron iron by accessing the rheostat. I had to do that with mine. I set mine for 405F – 410F. That made a huge difference.
If you really want to bag it, let me know.
