Looks like a good compromise for your bulkheads Mike...I used the same technique since the 70's for surfboard ding repairs, catamaran hull repairs, sailboard ding repairs......in that case it saves a lot of sanding, mimics the curve of the rail, keeps the cloth repair compressed, all with minimum work...once used it to save a bottom laminate when a free-bagging vaccum bag job on a sailboard bottom went bad. Your bulkheads are a nice application of the concept...
