Buy a stick of ptex from the shop and melt it in. The roughness of the coreshot should hold to ptex in.

It's so big you have to cut it out. You can cut that out and they have a different material then ptex that you use, not sure what it's called but I've seen our tech do it a few times. The material he used a lot thiner then a stick of ptex but it's stickier then ptex. That's the only way I know how to do it with a core shot that deep. Good luck!

I had the same problem as u, I went to the shop and got it fixed but it shatered on the next day, so I got clear p tex(idk if it will work with black), and put some of the burned layer on, they I scrubed most of it of and put the usable clear layer, with that I had been golden and problem free ever since

agh thanks for the reminder, i need to go up to the local shop to get some damn ptex

and watch videos online about how to fix core shots, dont pay your local shop $50 for it, Im all about buying skis and boots from local shops to support the local dudes, but ptexing is a whole different deal

Black ptex actually holds better then clear ptex

Be sure to clean the area out- make sure there aren't stray, wiry pieces of base dangling all over. Make sure your skis are room temperature, then heat/begin applying ptex. You'll be surprised at how much it takes. Apply a layer, watch it sink/settle in, then scrape off the excess. Go back and apply more, rinse/repeat/scrape until your ptex layer is flush with your bases. Apply wax liberally afterwards (let the ptex settle for at least a few hrs though).

The only good thing to come out of last winter for me in Utah with our lack of snow is I got pretty good at ptexing my skis from all the shots I kept taking. Not a pro by any means but every shot I've fixed has held and when I show my friends they for the most part can't distinguish between my bases and where I fixed them. Good news is ptex sticks cost about $1 so shots become a pretty cheap fix once you figure out how to do it.

Don't waste your time or any money trying to fix this on your own. This ski needs to go to a shop and get a good base weld. Ptex will just crack and fall out of something that deep.

Don't waste your time with p-tex, it won't hold on the edge, you either need what is called "edge grab" which is the thinner, sticker stuff someone described earlier or just soak it in epoxy. That's what we do in the shop I work at for the bigger stuff. We do repairs and tunes on the rental fleet of Mt. Bohemia, which is a gnarly resort up in the Keweenaw Peninsula of Michigan. Some of the gnarliest coreshots possible come out of that place, p-tex and edge grab just will not stick. You just need to get some quality two part and completely fill the gash, and either scrape it level or we usually with pass it on the belt a few times to level it. Pretty much all that holds. Doesn't affect speed or anything, think of it in terms of surface area. Ten or twenty square centimeters of epoxy, roughly twenty thousand square centimeters of base. Epoxy is pretty much the only way to go if you want it to last.

I just put a shot in my skis as deep as OP but not nearly as expansive. its probably about 1.5cm by 1 cm and its right on the edge. Will the ptex not hold because its on the edge and just as deep as the OPs?

ive never fixed one near the edge

Ptex sticks are great for filling in shallow scratches, it's just not meant to fill in deeper hits. it is not real base material, and it doesn't wear like it. It will eventually end up cracking and falling out of a deep hole. And who knows how much water will get in to the core. This could compromise the structure of your ski, and in the end costing much more than getting a good base weld done.

Only way you're losing the epoxy is if you come down straight on a shark tooth so I'd say its the best course of action.
