About a million years ago when I was a kid I setup my slot car track in my parents leaky basement--bad plan. The rails in the tracks were steel (I am guessing these are the same) and they rusted in the high humidity of the basement. I was not able to fix it (sanding the tracks makes them rough, then the cars have other problems). If you buy the set, store in a dry place.
May I ask what they're charging you for shipping?Just ordered one of these. I may have to "give it a spin" around my office.
