so im gonna replace the plug for the battery receptacles on my sun dolphin sportsman and im going to run new wires for the boat while im at it. but i was wondering what kind of adhesive would be best for keeping the top half and bottom half of the boat where the rivets are waterproof. im thinking of a 2 part epoxy but if a caulk would work that would be easier to deal with and cheaper. so if anyone has any experience with this or other suggestions would be really appreciated.
