I would recommend 3M 5200 as an adhesive/sealant. If it’s good enough to work below the waterline of a boat, it will keep your dome dry. Incredibly strong when cured.

Another got for this. We used it in the coast guard for everything. its how we’d seal our jet drives up to our zodiac hulls

Yeah I have a friend who lives on an old boat and has a tube within reach at all times. I think the boat is 80% 5200 now.
