Last night Dan and I went to the shop to work on our cars a little and when we walked into the shop we found every bare metal surface in the shop covered with a light coat of surface rust ! 
I'm talking about the bare metal on my rpu project, Dan's new metalwork on his Mustang project, the tops of our bandsaw, the rollers and shafts on the bead roller, literally every piece of bare metal had brand new rust on it. These parts have been laying in the shop for months without rusting as long as we didn't touch them with our hands.
Dan had just been at the shop the night before and all the metal was clean and rustfree, and our shop is dry as a bone, no leaks. Something had caused the metal to rust overnight. I went into Don's shop next door and the bare metal in his shop was spotless, even the bare metal roll cage in his Capri, nothing was rusty so it was limited to our portion of the shop.
As I was walking back to our shop it suddenly dawned on me.........MURIATIC ACID !!!!!!! Dan had cleaned some mill scale off of the steel plates he was cutting for his Mustang tub job, and he bought some muriatic acid to soak the parts in. He was telling me how it removed all the mill scale in about 10 minutes.
I read the label on the bottle and it said "Highly corrosive to steel, wood, plants, etc, and fumes will travel a long distance." Evidently the fumes from the acid permeated the shop and attacked all the bare steel. I spent an hour with a huge bottle of WD40 and a rag, trying to minimize the rust until I can get to it and clean it off with a DA.
Has anyone ever heard of something like this happening ?
