So, my board miss some centimeters.
I need to fix this...
I take a piece of marine board wood and cut the piece that is missing
this is the 2cm marine wood profile.
I have used sandpaper to shape the piece and then with epoxy and a special structural filler i glued them togheter
And then shaped by hand
next step i'll use some carbon fiber to join the old piece with the new one and paint with epoxy and graphite filler.
