Replying to Best Epoxy for Repairing Bases?

Sorry for asking a question that is probably all over this site, but can anyone link me to the best epoxy to use to repair deep core shots that are exposing edge material on ski bases? I've heard of people using West System G/Flex, J-B Weld Original, and locktite marine... and I've read that melting p-tex over an epoxy repair can improve its performance too. Any gurus out there that can steer me in the right direction? I'm trying to fill about a 2" section of nearly blown out edge on my bases. Thank you!
