Got this 2321 about 6 months ago at an auction for what I thought was a decent price, and didn't notice either the gross stuff on the body or the battery corrosion which caused some rust in the walkways and locomotive frame. While I'm waiting for a new fuel tank for the frame to show up, I decided to get the body and internals sorted out
-On top are (I assume) some sharpie marks, including "375" being written on it for some reason (once on top of the cab, another further down the body).
-Around where the handrails and walkways go are some rust stains from those parts. I'm worried about washing the red paint away if I tried to clean that off, so it might have to stay
-Inside is more of the rust stains from the frame along with carbon from the motors, I've cleaned up some of it with isopropyl alcohol, being careful to not allow excess to go through the handrail holes onto the outside of the shell.
Any other ideas are greatly appreciated!
