[C320-list] Lead Fin Keel Coating Repair Advice - 2007 C320 MK 2

[Utility Comcast]

Crickets on this topic.  Everyone must be out sailing!

I ended up repairing the keel coating with West System Epoxy and fairing compound.  It worked well.  Project is done.

Thanks

The depth of the exposed lead from the keel is just really the thickness of the bottom paint and, I am guessing, the original epoxy barrier coat over the lead keel.  How would you recommend re-coating these repair areas?
