It wasn't my dory, but I've glassed the inside of the daggerboard, centerboard and rudder trunks on my most recent builds and can't recommend it enough. I also painted the inside of the trunks with epoxy/graphite mixture, FWIW.

It's all very easy to do before the trunks are assembled.

Have fun,

   The graphite epoxy paint inside the daggerboard assembly sound interesting to me. I've wandered about wear and tear on these areas over time. Was thinking about applying fiberglass on the inside trunk extending through the hull. How did you mix or prepare the graphite-epoxy solution?

Hombre,

I used a 50/50 mix, by volume, of graphite and mixed epoxy/hardener. The epoxy and hardener need to be thoroughly mixed first, then the mixture is slowly poured into the graphite. It's like mixing cocoa powder and milk - adding the powder to the milk gives a lumpy mess while the reverse order gives a smooth paste.

Graphite powder starts flying with the slightest puff of air. It also stains anything it touches dark black. Definitely wear gloves and eye protection and at least a dust mask, as well as old clothes.

Good luck,

Laszlo

   Thanks for the graphite tip. I will be following your lead on my daggerboard trunk.
