The bulkheads are now done with fiberglass and black epoxy on both sides. With a bit of violence I managed to put both bulkheads in place. Now they only needs to be gkued in place with some sealants.
After I sanded the old (damaged) name inlay away, I made a new one a glued this in place on the kayak bow. To hold it in place I wrapped it with nylon tape. The next morning when I unwrapped it - it was croocked. It was only like 3mm, but I knew I had to redo it. Otherwise I would only see the crooked angle every time i looked at the kayak. So I sanded the second name inlay off again and started to make a third one...
