I do agree Warren and where I am it is so dry that would be no problem at all. But then I dont have a rust issue in the first place unless it was very poorly stored over the years and/or the mice made a home in the set. The rusted sets are few and fair between so I can be a little more picky and would not consider something really rusty in the first place.
How about the folks that live in a humid area? They will have rust issues unless they have air con or they treat the chassis.
