Been quite dissapointed with the results of the last few tubes of sikkaflex I've used recently.
Admittedly, the surfaces were unavoidably damp when the stuff was put on, but you mention this stuff was put on underwater!?

Good price too!
certantly as good as sika, i use sikaflex as well but tube life seems to be short with sika for some reason soon as the air gets to it.
marine flex in my opinion does a good job had it on my shock seats with no dramas at all for 3 years stuck an anchor bucket down with it on top of flowcoat never moved.
we do underwater painting at work some times and needed a compound to fill in crevices to prevent crevis corrosion hence i trialed it and did some tests basic prep applied by mastic gun left to cure and not a bad pull off pressure.
theres also a mastic called swellseal also applied underwater and as it says swells on cure 350% not used it on a boat [ideal for sealing transom bolts etc] but have used it to seal steel plates on penstock gates where it meets the brickwork to make the seal.
as a tip for storing we use to use aquasure for mending dry suits which we kept in the fridge to give long life just take out 24 hours before use to bring to room temp might work with sika once opened.
hope that helps.
