I sealed that seam as well but do yourself a favor. Flip the boat upside down then put a strip of masking tape that is just about an eighth of an inch higher than the lip. This will catch the dripping that will want to go down and mess up the top of your boat. Don't wait until the epoxy fully cures before pulling the tape make sure you pull it after it gets a little firm and no longer tacky to the touch. Also check for any larger drips that may make it over the tape barrier.
What you'll find is that the tape kind of molds the epoxy and fills in those little nicks and cuts as well.
Once cured go back with sandpaper and sand off the sharp edge that will be left over. If you have larger pits like I did you might want to mix a batch with microbubbles and use a syringe to inject it deeply into the larger pits then do the above.
