I have done a good few boards now, note I said a good few boards, not a few good boards. bwaaa haaa haa. Anyway... getting better for sure but I still struggle to avoid bubbles just on the sharp tail rail. I just glassed another board with 6oz plus 6oz tail fin area patch (not round rails), so not too much glass this time, and I squeegeed it damn hard to pull everything super tight. I went back to see if cut lap was ready to cut, and notice some bubbles along the sharp tail edge. It got me wondering.... should I not be sanding the black to a sharp 90 degree edge on the tail, maybe it should be slightly rounded and then add the sharp edge using the hotcoat?
