I have finally finished changing the V3 mould and can now get serious about building the first one for sale.
It took quite a while to sand the changed area so it matched the rest of the mould well. I also had to work on some kayak orders which slowed the process down. I was also a bit discouraged when this side didn't work out as well as the first side. The first side just needed some careful sanding and it was done. I had to refill the second side three or four times before it was even close. The area altered is the different coloured spot on the mould.
