1st - welcome! *I'm no fiberglass guy but hope to be one soon by necessity *::) *but I think the gouge needs to be addressed. *It could wick up into the fiberglass and delaminate it and or make its way into surrounding wooden structures. *Guys on here use Formula 27 or Marinetex or similar stuff but you'll need to seal it up with some paint or epoxy because I know Marintex does absorb water.

Then again all of this is my inexperience overreaction because I cannot see the area you are talking about.
