Two unusual but very useful and crazy expensive tapes, if you have a boat: PTFE Film Tape https://www.3m.com/3M/en_US/p/d/b40070573/ https://www.3m.com/3M/en_US/p/d/b40070573/ (don't let that picture fool you, it is a tiny expensive roll. Known as "millionaires tape" with good reason). Preservation Sealing Tape https://www.3m.com/3M/en_US/p/d/b40068317/ https://www.3m.com/3M/en_US/p/d/b40068317/ (a bigger roll but crazy expensive and quite necessary when you need it).
