Water hasn't gone inside so probably that's why there is no swelling
I should probably use it as a left ski to protect the edge
I would say there is no saving that. You can try, but I think it is game over.
All above said, you have nothing to loose but a bit of epoxy! Good luck!
Nice. If you are lucky it will hold out for a while.
when examining the edge with a magnifying glass, i got to the conclusion that the edge was ground to level, but the base doesn't seem ground, maybe they polished everything and used a structure roller to refresh the base. edge thickness in that area is 1mm, and 1,5mm on the rest of the surface.
anyway the whole sandwich is stiff and there isn't any gap when flexing the ski, i was afraid of temperature variations that could turn moisture into expanding ice and crack the whole thing open, but the skis were held in a dry spot several months and i think all traces of moisture are gone
now i have to polish the epoxy so that the diamond stone does not touch the repaired sidewall
