Underside first :
Then the top :
The U2 had some love just recently, and I forgot to add pictures. All the little dings and scratches were first smoothed out with 3M red-spot glazing putty, then where needed, the airframe was re-sprayed in matt black. I then added panel lines with a soft pencil, added some decals, then blasted satin lacquer all over.
I am very happy with that, and she should look a lot neater in the air now.
