Ian, do you mind me asking where you source your balsa out from here in the GTA ??
.... sort of off topic.....
At some point I'm going to be over-hauling the trunk on the roadster to put some better audio in the car. I've done a fair amount if fiberglass work to build trim pieces but never thought of using balsa to form the shapes. What you've done here has inspired me but with regards to achieving something completely different on another part of the car!!
