The only reason I got started on this job is because one or two of the partial bulkheads had started to seperate from the shelf below and I wanted to glass them back again. The project just kinda escalated. I decided to do all of the bulkheads and corners and the hull/deck joint too.
I used layers of fibeglass tape (regular and biaxial) overlapping 2 inch, 4 inch, 6 inch and finally 8 inch.
The fiberglass tape will stick upside down, provided you keep the lengths less than about 2 feet.
