I'm not sure how they do it, but I know they did a bad job on this one...
|Quoting Go3Team (Reply 2):|
Someone went against the grain on that one. Horrible job.

The reason the bare aluminum AC 767 looks like it does is because it was previously painted.
|Quoting AirbusA346 (Thread starter):|
But who else does it on there 747's.
|Quoting Gr8Circle (Reply 4):|
I think the AC aircraft pictured above is done quite well....reasons why it doesn't look good in this pic are:
1. Sudden change of appearance - people take time to adjust to anything new..
2. The sky is cloudy, but with broken clouds....what seems to be a 'bad job', on closer inspection, is actually the reflection of the cloudy sky...take a closer look at the pic...

When the paint is removed and the surface is polished the pure aluminum (alclad) surface appears dull, because of this prior treatment.

this is beautiful...

studied Industrial Chemistry at University and I have to contest this statement. I know, you shouldn't believe everything you read on the internet, however the first sentence of the second paragraph explains why the aircraft's surface will never be 100% "shiny".
"A clean aluminium surface is reactive and will react spontaneously with water or air and form aluminium oxide."
For anyone old enough to have aluminium kitchenware, try a simple experiment: make a small scratch and you will shiny, bare metal. Leave in a moist environment and the "wound" will heal. This due to the formation of the oxide layer, which gives excellent corrosion resistance as can be read in the attachment
