Rudder foils are started

We do rudders and foils to order quite reguarly,with our CNC shaping the profile and sections,they are spot on each and every time,shipped either as the blanks only and you do your own finishing,or as in this case we are doing the shaping and finishing with white twin pack etch primer,leaving the customer to paint with his top coats.The black paint allows me to see when to stop as I machine the un wanted wood awy.
