I’m going to just expose my ignorance here. Does the Mac 25 have a deck core that can potentially rot from water penetration? There appears to only be gel coat and fiberglass without a wood core. My chainplates are leaking and need to be resealed. They are riveted on. I was going to remove them, clean everything up, use butyl tape to seal, then place new rivets. Should I also push some epoxy into the holes? I would think that’s only necessary if there is deck core to be concerned about. Any suggestions? Thanks guys.
