I'm rebedding everything on my Tartan 27 as part of a total restoration of the deck, including partial recore. The area around my chainplates was recored. I isolated the area directly around the plates with thickened epoxy to form a block to protect the new core.
I'm thinking about how to re seal the chainplates. My T27 chainplates emerge through the deck without a plate screwed to the deck. If I use butyl tape, do I need a plate to form mechanical pressure?
