i may be wrong but i read somewhere it may be in the region of 2000 kg??
Total weight of the paint load with the Wunala scheme a couple of hundred kg more than the 'standard'?

Chimbu, ain't that always the way? Measured with a micronomer and cut with an axe.

VH-XXX, Wunala was originally OJB. When it went in for a major service it came out in standard livery and one of the ERs went in and came out as Wunala. The differences between the two is that the engine cowls on the first version were included in the paint scheme whereas the ER has the standard grey cowls. You used to occasionally see a red cowl on a non Wunala and a grey cowl on wunala which is why they eventually went to the standard colour. It 'loses' something with the grey cowls I reckon.

If you have a repair, paint can hide all sorts of things.
And let's not forget how well paint can foster and hide corrosion.

multi engined,

Special paint jobs can add extra weight if it is just a rub and respray as opposed to a complete strip and paint (more expensive outlay).
I've always wanted to know when weights are quoted for paint jobs are they the weight of the paint in the cans or the weight of the paint after it is dried i.e. all the solvents have evaporated off.

Oooh, oooh I've heard some stuff about this!!

Now, the "parked" 743 is Nalanji Dreaming or something...the blue one. That was at Avalon, but I last saw it there a long time ago.

AA may have gone for the all metal look to save fuel initially, but latter day jets (not Saints) require a laquer to "seal" (?) & this makes up for any weight savings by not painting.

I've also heard of restrictions to aircraft with special liveries but they were to do with overfly restrictions. The colouring, in some areas, is considered to be like camoflage, hence the restriction. The BA/UA grey scheme was frowned upon in some quarters...allegedly...and this went some way towards their respective new schemes.

Don't quote me on any of this, but this is the stuff you hear at the gate when the gingerbeers are bored!

Clark, from 'Airbus' website

About 3,600 liters of chromate-free paint is used for three layers of paint (primer, customer-paint, top-coat) for an A380. Only 600 to 1,000 kg of paint stays on the aircraft. Each layer is only measuring about 0.120 mm......

I remember reading (and have now read again) that the first two Space Shuttle External Tanks were painted but that the practice was scrapped as the paint reduced payload and wasn't required as the tanks were expendable anyway.

Hmmm pretty one-time-use Tanks or an extra 455 kg of Tang and Astronaut Ice Cream... tough call.
