I love jets that aren’t painted. I know Boeing uses a film to protect the bare metal and it isn’t primer but it certainly looks like it. A 747-8F was scheduled for a first flight at Paine Field prior to heading to Portland for painting. It taxied out and lined up. I thought I was going to get a first flight for this jet. It did a high speed taxi run and aborted takeoff as is the norm but something wasn’t right. They taxied back to the ramp and shut down. They weren’t flying on this day. I was a bit annoyed!
