I have damaged the nose of my board. It's a JP FSW 2008. See picture below. I think it was originally damaged by previous owner and I have opened up an old wound by walking it into a fence post.

Now my question(s) is/are.

Do I need to do something about this?

What are my options for a diy repair?

Is it worth getting something down by a pro? and if so what would be the ball park costs? And who?
