Got a little adventurous for early season conditions and took a nice hit to the base of my Rossi Scratch. This is the first time I've ever had a hit this bad, and I was wondering if this is just something I should take to my local shop, or if it just able to be filled with p-tek or some other DIY fix. Looks to me that I got to the core, but really not sure if that ruined the waterproofing underneath or anything else. Any advice would be helpful. Below is the picture of my ski and the hit that needs fixed. It is roughly 7cm long as you can see.
