Laminate countertop miter seam

Does anyone have an idea of what I can use to fill the seam a little better and make it waterproof. The seam is 2 feet away from the sink. How can I protect it from a spill or when cleaning it with a wet rag. The piece were connected with Titebond 3 which is waterproof however this is a small gap, less than 1/32 of an inch. That is the closest I could get them lined up together. I was thinking of just putting a strip of scotch tape? The seam is not really that big or deep to get a product to fill it. Thanks for any help in advanced Jay
