Instead of trying to laminate it traditionally to the bulkhead, wouldn't it be a lot easier to just make a sheet on a flat surface, cut it to fit, and then adhere it to the bulkhead? It would be worlds easier cause you could do it on a few saw horses instead of trying to get it perfect on a vertical surface.
I'd use a piece of smooth formica or other flat plastic, as a flat mould and lay it up like you would in a boat mould. The results will be the same, but with much less work and less chance for a mess up.
