Another question: reproduction red wheels, for say Lionel 253, are obviously quite expensive. Therefore, I got a bunch of authentic wheels and threw them into evapo-rust. It did a great job removing the rust, and the paint as well--second effect was not desired. Now, would I mask all parts of the wheel except that which is supposed to be red, and air brush an appropriate red on them? Or would this not work or not look good?
Sorry I ask so many questions, but after destroying several motors and other parts of my trains, I am hesitant to resume working on them until I get better educated on what I should be doing.
