Good Morning.

The rotor material is Not what damages paint, it's the dust from the pads. If it is dust from their machining environment getting your paint dirty, and it is just from being parked in the parking lot, I would be more worried about your wife's lungs. She probably doesn't want to find transportation for the distance she would need to park to keep the dust off the car.

My Dad worked in a machine shop as a machinist machining cast iron, ductile iron, and steel valves and parts for 20 years. At one point his doctor told him his cigarette smoking was helping to keep the metal dust moving out of his lungs and to keep smoking until he got out of that environment. 3 years after he moved to a different job with less dust the doctor said he could quit smoking.

I would never knowingly buy a house the backs up to a 2 or 4 lane road that has a speed limit of over 25 mph. The yards of those houses have a gray tint due to all the exhaust brake and tire soot. The tint gradually gets darker the closer you get to the busy street. It is most visible in the winter when the grass is dead.
