Thanks guys, I think I got it. A couple of questions though: What's the best way to tape it, should I tape it across the joint in a few places, or along it [ie if the tape is 1" wide, 1/2" is on each sideall down the joint?

Also, the instructions I have say to coat both openings for the wing joiner , but then the next step is to put the joiner in one of the wings, and then coat the rest of the exposed joiner and ribs. I think it would make more sense to wait on coating the other opening until i coat the ribs and such? the only reason I ask this question is because I'm making sure I'm not overlooking something, like the epoxy setting in or something.

Thanks so much
Tom
