I was at Kennedy Airport last night at Terminal 1, and saw numerous Delta 767s and 757s, sporting any one of the 3 liveries currently in Delta's menagerie. I noticed in a few cases, that the livery on the nose was not congruent with the livery on the body. For example, a "new" colored 767 still had a black nose.
I've seen this before as well (British Airways, Lufthansa).
I was wondering why this is so? Are the noses painted at a different time from the rest of the aircraft?

Actually, if I'm not mistaken, the radome piece cannot just be painted over, but has to have some degree of tech. certification due to the equipment inside. (Just as the rudder on some aircraft has to be re-balanced every few paintings.)
Consequently, they have to use radomes that are cleared to go. These might not always be in the livery you're working on if you have three out there.

I just flew a 757 from DTW-ATL and the 'plane was in the "old old" colors and the radome was in the "new old" colors. I think this has something to do with the radome cant be painted in typical fuselage paint, it needs special paints so it doesnt interfere with the radar inside, or weaken the radome.

Radomes are made from composite material. Behind the radome is the weather radar antenna. There can be no metal in front of the antenna or it would not work. The maintenance manual is very strict on the amount of damage a radome can have, for obvious reasons. Usually just a few paint chips, anything else and it is replaced. A airliner will have many, many radome changes throughout its life. So they usually come out of the box already painted.

It is hard to say how long a radome will last. It could be years or it could be days. A bird strike could do alot of damage, a lighting strike could put a pinhole in the radome. Day to day wear and tear can cause the paint to chip, erode, or the fiberglass to delaminate.
As part of the pilots or mechanics walk-around, the radome is allways carefully looked at. As mechanics, we don't repair the radome in the field. We replace it and it will be sent to a repair shop and they will determine if it is repairable.
As for the cost, I really don't know, but I am sure it is expensive.
