Messy to work with but…
Water doesn’t stand a chance of getting through this stuff even in a pool in chlorine and direct sun, best I have used.

Best silicone I ever used
Used almost the whole tube during the process of restoring my 16 foot aluminum boat.Stuff is great holds tight and is incredibly flexible. I had no issues with it drying, 24 hours was enough but I was using it in 80 degree temps. Only issue I ran into was breathing it, very strong odor especially if you're laying down a long thick bead. Used it to seal between transom and splash well and for all bolts and screws going into/through the transom. Boat always had some water in the bilge after a day on the lake, not a drop comes out now when I pull the plug.
