I started in the morning with first some extra carbon pieces to fill the channel more and I then put some glass bubble / aeroseal putty filler on it and I finally put a peel ply on it. I than started sanding the white primer. In the afternoon I gave the boat a second layer of white primer on spots where was not enough. After a tea break I started with painting the underside of the cockpit floor inside. The corner needed some extra paint to get it completely white.
