Also, Alclad is "corrosion-free" because it's 𝙖𝙡𝙧𝙚𝙖𝙙𝙮 𝙘𝙤𝙧𝙧𝙤𝙙𝙚𝙙. Corrosion is literally the conversion of a pure metal into a stable metal oxide, and Alclad's "protective layer" is, as you said, aluminum oxide.

While black paints impact on the air conditioning is fairly irrelevant at cruising altitude, the UV light absorption and associated heat is not. Parts heat up and expand due to that heat, from either UV radiation or friction, then those parts change shape. That is why typically aircraft companies only allow white paint on Wings and control surfaces. You can design for the way different colors cause your wings to act, but it is much simpler just make everyone have white wings and make the airline figure out how to incorporate the white wings into the the paint design.

Everyone knows a new car smell, *but are you ready for a new plane smell?*

"But Russian manufacturers paint them in yellow. We're actually not sure why." Well, since the only reason to spend the money and effort to make the yellow zinc chromate green is worker safety, I think you found your answer.

As an American, I found your joke about our weight to be hilarious, well done.

"Which is equivalent to about eight passengers, or six Americans. I'm joking of course. Three Americans." He's out of line, but he's right.

"About 1200 pounds less, which is equivalent to about 8 passengers, or 6 Americans - I'm joking of course... 3 Americans!" I did not expect to crack up during this video. Well done, sir.

Just as an aside, it used to be (no longer sure if it is the case because it has been a while) that one of the primer coats on US nuclear submarines was yellow. Basically the same yellow that you see in one part of the clip here in the paint can. This got covered by a layer of adhesive and then the tile coating... but for a while we all walked around singing the Beatles song ;)

9:10 I see what you did there, and I'm appalled. That's TWO Americans, buddy! Give us the credit we deserve!

The SR-71 Blackbird, for example, was painted black because the color actually helped to radiate more heat away from the plane as air drag and compression heated it up to immense temperatures

It's surprising just how often airplane's paint gets stripped off and then painted back on

I work for an airline company just across the runway from American's Tulsa Heavy Maintenance facility, and I know a bunch of American Airlines A&P and engineering guys. They tell me that the reason American started painting their aircraft is because the carbon fiber body aircraft MUST be painted to protect the material from the elements. But American did not want half their fleet in one livery, and the other half in another, so they started painting all the aircraft to keep the look uniform across the entire fleet.

you also have to paint CF because epoxy is UV sensitive. and a lot of places you see "that carbon fiber" look, have extra steps to cover the CF in something not transparent to UV but translucent for visible light (which is more expensive than paint) that or they make it out of CF, and then use a hydrographic water transfer to cover it with a picture of CF, so you think you are seeing CF, and it is CF, but your arnt actually seeing the CF.

The green on the exterior of Boeing planes is an acrylic coating that protects the skin panels during the assembly process. It gets stripped off prior to painting. All aluminum exterior panels are anodized, which forms a layer off oxidation that protects the top layer of each skin panel. Anodizing is used extensively in aircraft manufacturing.

My favorite part was the C° 🤝 F°. I'm glad that they can agree on at least one thing. 11:43

The green tinted coating on new unpainted Boeing aircraft is a temporary acrylic coating. The individual skin panels come already coated from suppliers. This is standard for almost all aluminum sheet metal. The corrosion protection primer BMS 10-11 comes in both green and yellow. I have many pairs of jeans stained with the stuff.

5:34 ahh yeah the world famous bomber the f4U corsair

Pretty cool seeing WestJet being used as the painting example. They always have a few 737's parked near the vehicle exit at YEG terminal; and I know an instrument tech that works for them.

What gets missed here is that the carbon fiber re-inforced plastic of the 787 needs to be painted because it will degrade under the UV rays of sunlight, so that would be the reason you won't see pretty black carbon fiber planes.

the translucent green shades on the fuselages of the aluminum Boeings is an anodize coating, it's not paint. It's cleaned with a solvent before painting. The pastel green coating is Hexavalent chrome, which is very toxic... the white interior paint is epoxy white, used to help prevent corrosion from the lavatories leaking and such.

"Which is equivalent to 6 Americans, I'm joking of course, 3 Americans" killed me

As a college kid in the 1960s, I worked in a paint shop at Boeing's Renton plant, building 727s, 720s, and C-135 "looking glass" versions of the 707. Everything that came through our shop was painted zinc chromate green, but Boeing referred to it as SRF, meaning solvent resistant finish, no reference to corrosion resistance which it must have also been.

Carbon fiber construction is not corrosion immune as suggested here. You are right that it is much better, but there is still a huge importance placed on galvanic corrosion. Carbon fiber is conductive afterall, so dissimilar materials can pose a huge problem. However, it is a big difference in the amount of money spent combating corrosion like you mentioned.

What you are seeing is the primer coating. While the yellow/green/and sometimes brown color of these primer coatings come from the added chromate corrosion inhibitors (Barium Chromate and Strontium Chromate are modern choices), the primary function of this coating is not to be the main corrosion inhibition mechanism. Aluminums are already treated with a chromate based chemical conversion coat BEFORE this green coating is applied. They've simply added chromates to the primer in order to help corrosion performance even further. The main purpose of the coating is to adhere to the metal with a strong bond because paints and pigments generally do not. It is also designed to be abrasive resistant, scratch resistant, flake resistant, impact resistant, and it is intended to provide a physical barrier (not just chemical) to keep electrolytes and oxygen away from the aluminum metal. In the case of fuel tank interiors, it needs to also be chemically stable against the harmful fuel additives as well. Then the topcoat goes on which protects the plane even further, though that's the layer that's primarily intended to be pigmented and provides less protection than the primer. The interiors are primed but not painted because the physical barrier against abrasion, scratching, moisture, and other mechanical damage from human interaction helps as well.

"I'm joking of course... 3 Americans" lmfao

And to think you got popular with your shorts, this was far more informative than any half hour show on the discovery channel, good job.

I made parts for Boeing, fairings, molar flares, lens housings ect. that green exterior layer is a semi-gummy protective layer to help resist scratches. We would polish the parts to a high shine on the exterior face, and paint the anti corrosion color on the inside (which always smelled like roasted peanuts to me for some reason) and then spray the polished side with this gummy green paint and then wrap in blue film and foam for shipping. At the 8 minute mark they are hosing the plane down to reveal the polished exterior side with what probably Acetone which is what we would use if we messed up the protective coating and had to spray again. Just wish the job paid more, was a good gig but doesn't matter much if it doesn't pay the bills.

I thought the Aloha Air accident was due to repeated stress due to many more rakeoff/landing cycles that a short distance aircraft experiences compared to industry norms.

Heat does affect aircraft structures. When the B-29 was built in Georgia during WWII the plant had to be air-conditioned. The heat was bad for the workers and the aluminum expanded too much resulting in loose rivets when the aluminum was cold.

One of your best videos!

Your shorts are alright, but I really love your long form videos!

Thank you for answering one of the questions I always wanted to know the answer to

10:17 If I’m not mistaken, the reason the rudder is painting is so that it’s perfectly calibrated in the factory and can’t do so if it’s painted in the regular paint shop like everything else. The primary reason is not that it’s a composite

Your humor as always gets me

8:00: That green coating being washed off is a water soluble covering added before transit from Kansas to Washington. It is not zinc chromate primer.

At times, the different colors of zinc chromate were used to indicate how many coats of primer had been applied. Yellow might have been first, followed by a coat of green, for example.

The air newzealand planes look sick

You never disappoint. Each video is a real banger.

super cool seeing that old school American livery on the 737. I've actually piloted that aircraft shown at 0:20!

Air New Zealand paints the first aircraft of each model series black, I.E the first A320 to enter service was black, all other A320 are white.

The dark green you see on 737 fuselages on freight cars and prior to assembly is a temporary coating which is washed off before painting, not zinc chromate primer.

Very informative, thanks. I never knew that beautiful shiny metallic green in fresh-from-the-factory aircraft was paint. I somehow thought the special alloys manufacturers would use nowadays perhaps had that colour naturally. My knowledge on aircraft cladding stops at WW2 Aluminium!

Great B-roll on this video!

Just recently subscribed to your channel and glad to see aviation being focus on this weeks videos!

So that dark green coating on the exterior of Boeing airplanes it's called a temporary protective coating "TPC" as you included, It is not a paint it's removable with solvent. Is to protect the thin clad aluminum on the exterior during manufacturing. Typically Yellow corrosion protection is used in fuel tank areas, green and on fuel tank areas.

I've been wondering this since my childhood!!!!! Thank you!!!!

Fun video! Thank you.

The "3 Americans" joke made my day!! Thanks!!

Me when war thunder: -1000 silver lion

Great video, IMO. I learned a lot. Thank you. ☮

0:41 that railroad crossing is in my old city of renton, washington! Theres a park to the left and apartments in front.

ryanair landing gear is made out of bedrock

"which is equivalent to 8 passengers, or -6 americans- 3 americans" 😂😂💀

when you started the Warthunder section of the video, i was thinking "ugh not again'' and i was about to change to a different video, but when you said Warthunder, it struck! i play that all the time! not even 5 minutes away!

Absolutely Love your videos and Humor!!!!

I want to see a rgb plane because disco and balanced speculations for “durability”

"The fight against corrosion began with automobiles..." *sad pre-dreadnought noises*

It's fun to see scenes from around the Boeing 737 plant down the hill from my house. Yes, sometimes I have to wait at railroad crossings to watch green fuselages travel to the plant for final assembly.

I love the c/f handshake, lol.

The Boeing aircraft you are referring to are actually are coated with a lacquer to protect the outside metal from scratches during the manufacture and transportation. It's referred to as Spray Lac or Spray Lat, depending who you ask.This coating is removed just before the airplane is painted. Even after first test flights. This is why airplanes can be seen flying with this coating on.

Simple. The green plumage is the hatchling colors. When they mature they’ll take on the adult coloration.

Very interesting...thanks

4:14 I love how those planes in production are Ryanair lol

"Black planes are rare" Me, a New Zealander: "that's news to me"

The Mach 2 Concorde was always white to keep it cool. It still stretched 6 to 10 inches in length due to this thermal expansion.

Great video and research. I had no idea what was the history of the Green Zinc Chromate coating.

Total stream of consciousness video. Loved it

i swear the videos get hornier

I guess that the "interior green" of WWII US planes was because of zinc chromate plus the need to avoid yellow for a more eye-relaxing green. Also, Japan used a sort of turquoise similar to the Soviet planes interior.

It's off for it's first permenant paint job, that green surface finish washes off with solvent. I used to paint brand new aircraft with this temp sf on. The yellow was an epoxy primer which had to be re-done due to moisture absorbsion by the time it arrived anywhere.

Great video

As someone who works for Boeing (spirit aerosystems) I see these big green “pickles” daily and deal with them constantly, the paint is still highly carcinogenic😅

War thunder is a game were suffering is... The game. But we still play it because we like to suffer.

I love your channel. And your sense of humor.

9:02 THE JOKE HERE MADE ME CRACK UP SO HARD DUDEE😂😂😂

I have the biggest grin on my face because something mentioned New Zealand.

8:46 Aluminium Oxyde technically isn't corrosion-resistant. It is simply already oxydized (corroded) which means that it cannot be corroded any further

4:04 is a very nice demonstrative 😍

Small world, I was suggested this video while waiting for the first coat of greenish yellow zinc chromate aluminum primer to dry on a batch of my Guitar amplifier chassis and panels.

11:00 cabin humidity? How do composites affect cabin humidity? Is it because now we can have higher humidity in the air without worrying about corrosion on the plane?

I watched another video recently regarding the painting of aircraft. It said that tests by U.S. Army Air Corp during WWII concluded that painted aircraft required considerably less power to maintain cruising compared to unpainted, bare aluminum. The weight of the extra fuel required was a few times more than the weight of the paint. I'll have to search and try to find that link.

Literally went to the airport shown in the opening B-roll just the other day for a flight lesson. Pretty interesting to see all the “naked” planes out on the tarmac.

There's benefit in cleaning/polish in fuel savings. I knew a 747 pilot who swore up and down about American waxing their 747s saving something stupid like 10% fuel and flying faster.

I build scale model airplanes, and the interior of every plane from WWII is painted either zinc chromate yellow, zinc chromate green, or a combination of the two. RAF planes have their own interior green color, as do Russian planes. The colors simply called "RAF Interior Green" or "Russian Interior Blue/Green". The amount of money I've spent on bottles of these colors is insane. So glad to see a video explaining why this is done.

Having worked in the aircraft industry for a few years, I believe you are talking about zinc chromate primer, you say yellow but it looked like it was more of a chartreuse ( slightly greenish yellow). I paused the video to add my comment, posted just before you said it.

good work.

American airlines = built different

6:00 If I had a nickel for each time classified military documents were leaked on War Thunder I'd have 6 nickels. Which isn;t a lot but it's weird it's happened 6 times.

I’m an a&p apprentice and work mostly on 40-50yo aircraft. A lot of them have the yellow primer but we clean and then spray the surfaces with green primer following a coat of dinotrol. It’s amazing how little corrosion these planes have

I was a painter at American airlines in the 90s. The people buffing the aircraft were having shoulder problems. I watched the trials of the robot buffer on a 727. It really sucked! But not hard enough to stick to the plane with suction cups.

Hexavalent chromium is highly carcinogenic. Interestingly, a different form of chromium, in tiny quantities, is an essential nutrient.

"The most capable carrier-based bombers of World War 2... wore pink underneath!" And they were made by ladies too, don't forget!

Air New Zealand livery just looks so good !!

Well, that was extremely interesting

Black painted planes WILL get hotter when they are parked or aren't at 30 000 feet. If maintenance is taking place in a open area and not a hangar the workers will get melted from that heat.

5:36 The Vought F4U Corsair was not a bomber aircraft, it was a fighter. Sure, it carried bombs and rockets in case it needed to perform strike roles, but that still doesn't make it a bomber.

Good job

09:06 THAT burn would take some time to heal.
