Picure 1 shows a deep scratch one one spar. Probably not a problem, but I think I'll take advice.
Picture 2 shows part of the other spar, where some rivets have not been countersunk (unlike the first one). Again, this may not be a problem but I'll check.
Vans advice is to file/sand out the scratch. No problem with different rivets, apparently. Blue pen marks indicate they were in spec when inspected.
