I was hit by another skier and either his edge or ski tip dug into the very top of my sidewall and tore and separated the topsheet of my iM82 ski a bit. See included pictures below. Besides that the torn topsheet is very sharp, I am also concerned about further separation and water damage. I cleaned out the area with a razor and tried epoxying both the separated area and the tear with some Devcon 2-ton epoxy (12 hour) using clamps and wax paper-covered heavy duty metal strips. I let it cure for 24 hours solid at room temperature. But afterwards, nothing really held very well together. The epoxy was very brittle and I could easily take it all apart again with fairly light pressure. I was pretty careful to try to use equal amounts of both the resin and hardener, but maybe I didn't. If I look at the tubes, it almost seems like I used more resin than hardener. Maybe that was it, maybe not. Perhaps I should try some different epoxy and/or a process. Any suggestions? I don't want to keep having to do this over and over again. I will probably try cleaning out the area with some alcohol again too.
