There is a sealant caulk made by 3M called 5200. It is used to seal fittings under the waterline on boats and is permanent, unlike any other caulk or sealant. I have used it many times and it is the flat out best there is, but expect it to never come apart or leak again. It comes black or white, and also a less permanent version called 4200.

Best stuff on the market
There's blue = slow setting
Red = fast setting
Lowes and Home Depot care it.
Keep in mind it's meant to be permanent
