Temporary fix
Bob, I hate to say this but you know that is just a temporary fix. Eventually the UV from the sun will eat through that exposed sealant (silicone? 5200?) & rot it right away. Not only that, it could be just limiting the water getting through which means that a little water still could be getting in there & you might have wet coring.The sure fire fix is to remove the offending port/hatch & completely rebed it. This will not only "cure" the leak but hopefully prevent any damage to the coring. LaDonna
