We are resurfacing the decks of Mango #29 right now.
We sanded off the loose "molded-teak" and have sealed with a 2-part high-build sealant. Then we will top with some sort of a surface treatment / non-slip.
The contractor we are using has done several boats with the same technique.
I will dig up more information about the steps and materials we are using. Feel free to reach out to me if I don't get back to you quickly enough.
