building a wooden boxfin

has anyone built there own boxfin. i made a wooden one and tried to glss it but i got an airbubble around the fin. does anyone know of a way to do this. i was thinkin of putting strands of cloth in the resin and just painting on a bunch of coats. do you think it will be strong enough. any feedback helps.

it should help with the making of the fin itself, they are glass-ons, but im sure it will help with making a fin that will fit in a finbox
