So nice - it really reminds me of the interstellar object 'Oumuamua that flew through the solar system a couple of years ago -
And here is the board with the laps across the bottom deck all ground down.
The fill coat got to harden while I was at work.
And I got home, ate dinner, then applied the fill coat to the bottom deck. It was mostly dark so we didn't take pictures, but I'll take a few pictures of the board tomorrow before I start to sand down the fill coat.
