I had no idea the paint layer was this thick on these airplanes. Christ, it must weigh a ton.
And how the hell do they apply it? Looks like a powder coat job gone bad.

I vaguely remember either American or United when they redesigned their livery (colorway in plane branding speak), the CEO made a point of saying that they were going to only have predominately metal with only a little paint because it was going to save a gazillion gallons of jet fuel a year...of course his interest wasn't in the carbon footprint/ fossil fuel use but was telling stockholders it was going to save them the gross national product of a small nation every year.

CC to "irrational fear of flying" thread.
A-350 has a carbon fiber fuselage, needs a layer of metal mesh to provide lightning protection.

That’s one helluva paint booth…

hey, how lucky can one man get.
I would say that bad prep work ruins any paint job.
Which might be apposite: assuming the metal mesh is aluminium it will expand by about 60mm over the length of the plane in a 40 oC temperature swing while the carbon will not*. The difference might be enough to cause them to separate when the planes are exposed to extreme conditions as in, ferinstance, Qatar.
* Carbon fibre itself has a negative Cte, that of the composite will depend on the matrix and fibre orientation etc.

I had the opportunity to work on a plane livery project several years ago. It was very interesting to learn about the effects of weights and colors. I didn’t get to see the paint applied, unfortunately.
Not an airplane but kind of interesting. In 2012 we were part of a naval exercise out of Pearl Harbor. The Russians sent one of their cold-war vintage guided missile cruisers. It was moored at Pearl. If you got close enough, you could see the deep "texture" of the paint where coat after coat had been applied over rust. I walked around on the ship and passing through a hatch, I put my hand up against a bulkhead and I could feel paint crumbling. I think the ship was literally held together with some sweet Soviet era lead paint.
We had a cool photo of our combined multinational task force with the US carrier as the centerpiece. We could only go 5 knots so the Russians could stay in formation.

Do you ever stop repainting a Navy vessel? I’ve been under the impression that it’s constant.

On nuclear ships it's: one coat for dust, two coats for rust, and three coats for contamination.
Navy ships have a process for painting and the first step is to prep the surface by removing the existing paint with a needle gun. I learned to sleep through the needle gun cacophony as easily as I got used to living under catapult one on my 2000 deployment on the IKE. Woodpeckers make me sleepy.
