Quite a while back I did some research and came across many people who's trunk developed a surface rust spot under the chrome strip near its ends, even appearing shortly after delivery.

I'm only guessing but perhaps they had some kind of electolysis issue causing the rust between the chrome strip and trunk and is one reason why it was not on the '04's.

Purely just guesswork though.
