This pink mystery substance on the bottom of the hull covers the keel. It looks to have been sort of smeared haphazardly in place. Looks like bondo, smells like bondo... What is the purpose of this? Edit: I've since been told by the C-Dory factory that this is Thixo and it was added for "reinforcement". I really don't see what it's reinforcing. It bothers me that I can't see the glass over the keel so I'm considering removing it and replacing it with some epoxy and mat.
