Repairing Cracks on a fiberglass boat? - boat trailer repair ontario

I bought a old fiberglass "bathtub" type boat because he wanted the trailer that was in progress. Now I think to try to the boat cosmetically and give my father. The boat has small cracks in the outer layer of fiberglass everywhere. Just wondering could fill the cracks with Bondo or something. As I said, are the cracks outside the ship and it is only for looks. The boat has no leaks.
