Hi Brian,
I'll get some interior photos up soon. As far as the methodology for cleaning, I used Evaporust for the heavier rust and then Blue and Rust Remover by Birchwood Casey. This stuff is for gun restoration so I figured it would work. I soaked #0000 steel wool and used it to clean the remaining rust in the various cracks and crevices. Like I said it was a tedious process but the results were worth the effort. I have another one I'm working on and I'll post some pics of it too (if anyone's interested).
One more thing, if you try this be careful about getting either chemical on the interior. If there is any rust hidden below the paint it will remove both rust and paint. I found this out the hard way. Luckily I didn't lose too much of the original finish.
