Top, (flat portion of rib, bottom on this pict) got some 3M 375 packaging tape, then a mixing stick JB KWIKed to it. The bottom of "thumb" got tape and also was JB KWIKed to stick. Sides of fin were taped, any gaps floxed, all scuff sanded and laid up 3 BID.
Time to get on with middle rib mutilation which by far is more evil.
