One Comment About Butyl Tape in Underwater Applications:
I work with underwater buoys that are deployed as deep as 2000 meters. The main body of these buoys is comprosed of a glass sphere that comes in two parts. The hemispheres are mated, a light vacuum is applied, and we seal the joint (on the outside of the joint) with butyl tape. Standard, off-the-shelf, glaziers butyl tape; and the tape has remained intact, pliable, and removable after as long as two years submerged.
(edit: we then wrap with a layer of Scotch 5200 electrical tape as a mechanical protectant)
While this is not a statement that it is the ideal candidate for Brak's application ; I can state emphatically that it will come out of the water in nearly the same state that it went in. Personally, If I were to do this job I might choose it over 5200 for the ability to remove it without using the nuclear option.
