I agree with Chris except for using 5200 as the sealant externally on the seam. You want something that will flex with any movement and temperature variations. If the deck was removed and rebedded, then use 5200.

5200 dries like cement, and is for permanent adhesive bonding, not as a filler applied to an external joint.
