5200 is the best sealant for the Marine Industry if you're looking for strength and longevity for joints above and below waterline. However, if large areas of the joint will be exposed to UV, try selecting an alternative 3M product, such as 3M 4000 UV.

3M Sealant whether brown, mahogany, or white is absolutely the best for any sealing job. I use white fast cure on my RV windows and RV roof. Compared to even the best silicone caulk or RV roof sealants, the 3M is far better. It is definitely worth the extra cost. It is able to be painted too. Try it, you will see what I mean.
