Failing that, can I
"seal" it somehow so it doesn't get worse? It's not that noticeable
yet, so if I could seal it and color in the slight split to nearly
match the formica I think it might be OK.

I'd use a colored stain or paint to give it the color and they coat it with
a marine or spar urethane to seal it. Perhaps there is an epoxy sealer that
would work better.
