Don't panic. The metals room looks like a disaster area, but it's just dust.
I painted a new shelf frame this evening. I used white this time, and despite the use of a drop cloth, the metals room floor is momentarily covered in dry overspray. I suspect this has always happened, but black dust just isn't noticeable.
The frame should be dry to the touch by morning, so if anyone absolutely has to move it, go ahead. I'll need to flip it and finish painting later this week. (likely Wednesday night) Once this is done, I'll vac the floor and any covered surfaces.
