: I am wondering how
: to get full water proof fiberglass edges to protect the wood on
: my sections without any air under the glass.

Consider not having the fiberglass go around the corner on the outside. Instead, on the outside, just run the glass right up to the edge of both the bulkhead and the hull to make a very sharp corner. On the inside, fillet well and run fiberglass across the joint and it should be plenty strong.

If you do want to run it across the joint on the outside, it would help to run mulitple layers of a thinner cloth (3 or 4 oz) instead of one layer of thicker cloth. And at a 45 degree bias, as someone suggested. My guess is you could get a between a 1/8" and 1/16" (2 mm) radius. After laying the cloth you might wrap it in plastic kitchen wrap and/or some weights to force it to lay down. Visit it every half hour or so as it is curing, so you can push down any bubbles in the late 'sticky' stage.
