Mike has an interesting idea with the liquid polysulfide. Maybe that creeps down into the gaps better.

After the epoxy has been cut for the new chain plate slot, I filed about 1/16" to 1/8" gap around the chain plate deck. I also gave the deck a chamfer (sp?) or bevel so I can get more sealant in there. I have used regular polysulfide (LifeCalk) and forced it down into the chain plates with a putty knife until it really oozed out from below decks. Afterward, I like to tension the rig immediately.

What I like about the deck plate is that it shields the sealant from UV.

One year I used 3M 4200, and it lasted about 8 months before it started to progressively weep. I don't think it's elastic enough.
