Less than a ton of paint on a early 747.

Bringing the total paint required for a 747 to 1850 lbs. A gallon of paint weighs 11.5 lbs, meaning 160.87 gallons of paint will be required to paint a 747. Cost of paint A gallon of Sherwin Williams Poly Urethane based paint costs the public $187.43 / gallon on Sky Geek. That's a total of $30,151.78 worth of paint for a 747.

And on a 737 (different source):

paint on a 737 adds about 555 pounds to the weight of the aircraft. ...

FYI, not wanting to get into a urine contest, but when I mentioned the weight on a 747, that includes the part(s) of an airplane that only a mechanic would see, i.e. say the "46- Section," of a Boeing 747. The 46-Section is approx. just after where the wings attach to the plane, and goes to the rear of the plane, just before the "Tail {Vertical Stabilizer}-Section."

This section alone uses 80 gallon's Boeing "702 White," two people to spray, in an 8 hour bar to achieve completion. this is done pre-assembly. (Two part paint, so multiply 80 times two.) One part paint, one paint hardener.

The 44-Section, basically where the wing(s) attach to the airplane, use's 60 gallon's Boeing "702 White, two people to spray, in an 8 hour bar to achieve completion. this is done pre-assembly. (Two part paint, so multiply 60 times two.) One part paint, one paint hardener.

The 41-section, i.e., the nose section uses most times 60 gallon's Boeing "702 White, two people to spray, in an 8 hour bar to achieve completion. this is done pre-assembly. (Two part paint, so multiply 60 times two.) One part paint, one paint hardener.

I'm not listing all the part's of the airplane, but again just the "Pressure-Dome," approx. 10 foot dia. Goes between the 46-section and the Tail section, uses approx. 10 - 12 gallons. one person paint job.

Hint, all of the above uses a two part green primer system. All fuel cell(s) (that would be the inside of the wings, and the bottom half of the 44-section) use a special fungal resistant yellow primer.

Not to mention all of the different (Dia.'s & Length's) hydraulic lines that get primed & painted.

I could go on, but this should give a general idea.

Hey steve86, FYI, as a guy who does enjoy throwing gas on a fire, wondering just how the hell is your calculator doing this morning. via my other response with paint amounts for different 747 body-sections.

I'm not sure just how you enter this into a calculator, when your trying to be the smartest person in the room (Earth to steve86, your not even close) I have no idea just how much paint is used in the Tail-Section, where I worked in the Everett (Washington state) Plant (40-41 bldg) (at the time, it was said, you could tear off the roof, put the Seattle King-Dome in the building, put the roof back on, and still have room for parking.) we didn't paint any of those sections. We only painted the "vertical stabilizer-part," that moved, so as to turn the plane left /right directions.

"vertical stabilizer-part," one man operation to paint, approx. 7 gallons (one part paint, one part hardener.) PS, the only reason this sticks in my head, was you would use the "ONLY" 5-gal spray-pot, otherwise it was "20-gal spray-pots," that could be filled to 22 gal. capacity. Had the little "AIR-MOTOR'S" to constantly stir the paint, inside the pot(s.) We cried and moaned, begged for bigger pot's. Never got them, at least for the 5 yr's I worked their. In truth, I don't even know if a bigger spray pot was available, now that I think about it. But we sure wanted one.

I worked in what was called the "Body-Section & Detail shop." Now, let's say on a 747, you had 300 seat's, all had say a cover plate for a ash-try, needing paint.

Bingo, you got it, that's 300 PAINTED ASH-TRY COVER PLATES.

If it help's, you only use approx. 1.5 gal paint, to paint/refinish the Pilot's & Co-Pilot's console(s) and "seat-bracket(s.)"

So, steve86 just how many THOSANDS of parts on a 747 require painting, inquiring minds would like to know.
