I was just wondering how airlines figure out how much a new coat of paint would cost to apply. For example, does blue paint cost more than red? What about the weight too - are certain colours more expensive?
Is there any way at all to actually figure out the amount of paint and the cost needed to paint say a 737 in a certain scheme for example?

BA777: A few years ago I was involved in painting 747's. If I remember correctly, from bare metal out, we figured about 60 gallons of primer (including catalyst), and 60 gallons of various colors (including catalyst), for a total of 120 gallons. The Crown Metro High Solids paint we used weighed about 10 pounds per gallon, so that works out to about 1200 pounds of paint. I don't recall that any one color cost any more than any other, but we bought in large quanities. With the strip, cleaning, and repaint, we figured about $147,000 per plane. Took about 10 days to 2 weeks, with a crew of about 15 per shift on 2 shifts.
I'm sure the major airlines and paint manufacturers can put their computers to work and figure out about how much paint any particular scheme will require. Regards,

Another thought. If that's true, then all the airlines can fly bare metal planes around as a cost cutting measure. No one will be able to tell what airline the plane is, but hey, the atmosphere nowadays is to cut costs as much as possible!
I hope FR doesn't see that idea - pretty soon their planes will be all bare metal.

"So does AA save money then in fuel costs because their planes have very little paint on them?"
Yes, they save money in fuel costs. However, bare metal is not actually bare metal. There is a special polish that needs to be applied on top of the bare metal to prevent corrosion. I heard somewhere that this polish is expensive compared to the regular paint, and it needs to be taken care of more constantly. I also recall hearing that the costs tend to even out with fuel savings so there's not much of a difference.

Actually AA advertises and is proud of the fact that their planes are lighter and cost less to paint ( yes there is the cost of the polish, however it would probably be miniscule compared to the paint)

2200 lbs for a DC-10? I think that's way too much. Then how would you explain this if you need 1200 lbs for a 747? A DC-10 isn't any larger than a 747 is it? 300 lbs for a 737 that makes sense. I remember reading somewhere how much paint a 747 needs when being repainted, but I don't remember the figures. I'll look it up in my books when I'm home.

Just out of curiousity, do these numbers include provisions for vaporization? It's probably quite difficult to calculate the true percentage of paint that actually sees the airframe (though I'm not familiar with av-painting methods).

Sharkskin: It's not really smooth, and yet sharks are very nicely hydrodynamic. It turns out that the surface consists of very small ridges. Experiments show that this reduces drag (from the skin) by 1-2%.
IIRC, CX were playing with this about a decade ago. They painted some of their planes with "sharkskin texture" instead of smooth paint. This decreased fuel burn by a minute amount. Unfortunately the paint job cost much more than a standard one, offsetting the savings. I am not sure how exactly the tests turned out in the end.

AA do indeed have paint on many parts of some of their aircraft....figerglass/composite fairings for example.
In addition, the entire A300-600 is painted, as AirBus does not like to deliver unpained aircraft, due to corrosion issues, among others.

Not anymore. If you notice all of AA's A300's have the bare metal scheme like all other types, just the rear section of the fuselage, the tail and the center section on the belly are still painted in gray. It was 10 years ago that American removed the paint on the aluminium skin, indeed to save weight and paint each time the aircraft is due for its MX D-check. But you're right, when they were delivered fresh out of the factory from Toulouse France back in the late 80's/early 90's they were entirely painted in gray to prevent corrosion on the aluminum skin.

I used to own a Schweizer 1-23G sailplane. The paint was pretty ratty when I got it so I had it stripped and repainted. Just for grins, we reweighed it after it had been stripped and it was 40 lbs lighter. (Of course, it had something like 5 or 6 coats of paint in some areas.) You really wouldn't think so, but paint is heavy and excess weight is one of those things that aircraft - any aircraft - don't need.

Here's a definitive article from Boeing, which says that net expense of operating polished aircraft are generally a bit *higher* than painted, due to labor required for more frequent repolishing than repainting.

I've heard from multiple sources that the reason for the AA A300 being painted from the factory had nothing to do with corrosion issues. It was actually due to an issue with the supplier of the fuselage aluminum. It was, in fact, that the color consistancy of the aluminum (sheet to sheet) wasn't as uniform as AA had hoped, therefore a descision was made to paint the aircraft, rather than having a flying "disco-ball."
