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.
Oh and the tape part you can skip, but it's not good to get alot of epoxy on your base. With the tape it should be flush with the edge, if there's some tape overhang, trim it off with a razor blade. Hope this helps.
my sidewalls are fine but my edges and bases are literally seperating on one ski. its not good. and im waiting for my show to hear from armada about warranty. my friend has another big edge problem too and both of or skis are about a year old.
I've had no side wall issues but my under foot is fucked. my base sits higher then the edge here completely meaning no edge touches the snow. plus i am miss a inch long chunk of edge on right side of the ski with armada printed on it tip
