The preassembled center section bulkheads I received from Vans came with some scratches and marks, mostly on the center section bars. I have attached pictures. It reminds me of the rough condition of the horizontal stabilizer rear spar reinforcement bars as received, which required a lot of work to smooth out. I was surprised Vans shipped these in this condition, given the admonition in Section 5 to sand out all scratches, no matter how small, and the critical importance of these parts. Given that these are already riveted, I think it would be a real pain to smooth out. Also, if I were to smooth them out, I would have to remove the anodization in those areas. I wrote into Vans to get their opinion, but haven't heard back yet. What do you guys think I should do?
