Trek - the rust is inside the tube. I can see rust around the drain-holes for the tubes.

did I mention that there is RUST in my PRECIOUS DARLING!?!?!?!

Maybe I'm too fragile and delicate natured to cope with a steel-framed bike. Even just a steel fork is exhausting. Imagine the panic, the utter hysteria, when I discovered the rust that lurks in bottom brackets! Oh, just the thought makes me feel like I need a lie-down with a cold compress on my fevered brow.

If I was half the butch I like to pretend I am (which would be about 1/4), I'd've called the LBS and asked them what to do already. It's more fun this way....
