I decided to make one last improvemnt on the V3 before starting on the first order. In the picture you can see the black line drawn inside the wheel well.
I will change the shape of the mould so the line is now the outside of the shape. This will reduce the area exposed to airflow behind the wheel a bit.
Here you can see the mould cut away waiting for the new shape to be inserted. Once the new shape is held in place I will rebuild the mould over it. Then comes the tricky part of matching it to the existing mould. Mostly its a lot of tedious delicate sanding.
