Took a week off to watch the Fall colors in the mountain

Back in the workshop, inventory completed: not a part missing in the hundreds listed in the inventory by VAN's. These folks are amazing, they really know their stuff about the kit business and this results in less aggravation for us, the customers. I have now to do some home work on the issue of priming for the wings. My preference is to minimize priming to only what needs protection: bottom line, I do not want to prime inside alclad parts. The question is then: what's left that needs priming inside the wings?
