A few extra pictures to show the process - for those interested
1st - Design drawn in vectors - in colour on the shell - all to scale so the masks / design fits properly when cut
2nd - The design split into parts and flipped ready to print to the cutter
3rd - The cut vinyl (carefully) transferred onto the shell - this is fiddly as you can see there's lots of pieces pre-cut applied in one go so I can remove pin stripes etc.
Finally a Picture from above - showing the roof
