Replying to Gash in the bottom of my snowskate

I have a single deck wooden surface skate snowskate.


Today was the first day I used it, in my backyard. When I was walking back to my front door, I noticed a gash in the base of the deck, on the side of the nose. I can see the wood, since it chipped the whole base to the wood. There is also a 3 inch long crack in the middle of the base. But, the wood on the side is visible(the way its made) so maybe the wood is made a way that moisture cant get it, cuz it would get in the sides...

What sould I do?
-Just leave it that way
-Fill it with P-tex or epoxy or whatever
-Take it back to the shop I bought it and warrenty it or whatever

Thanks
