Pictures not real clear for me bro, but I'd buy some epoxy from a hobby shop, run some packing tape extending about two inches beyond the said area (two inches running the length of the ski) and mix the two part epoxy and apply it to the area with a Popsicle stick........ Or take it to the shop. But if your cheap get the epoxy, mix just enough, and do the repair. It's what I do to my sidewalk gashes and I haven't had a problem to date.
