Experience wise, what seems to be the most durable paint for inside a stand. Obviously, it would need to be able to stand up to saltwater for extended periods. I'm caulking all the joints and will have about 8"all around the bottom to hold water in case something goes wrong. I also am taking into concideration a possible future MH over the fuge for a frag rack. Someone had mentioned "Kilz" before but, I seek your opinions and experiences.
