I'm moving to Outer Mongolia!

Tonight has been a total and utter cluster****. Mom's new retro-feel black and white bathroom was almost perfect- it needed only a thin line of black trim about the windows and for the radiator pole to be painted. We had decided to paint it black to make it an architectural feature. We researched and bought the high-heat spray paint that indicated it was designed for radiators. Apparently those designers believe you will be disconnecting your radiator and moving it to an empty lot to paint it. Black fine spray EVERYWHERE. All over the bathroom floor (OK, easily cleaned off so not too huge a problem). On the edge of the skirting board in the hall off the bathroom (glossy paint so again it cleaned up decently easily). All over the wood floor of the hall despite the fact that (1) the door to the bathroom was only partially open, and (2) that most of the hall in question isn't even in any kind of direct line from the bathroom. My mom and I just spent an hour trying to get rid of the fine black mist everywhere, and I'm not even sure we were successful- we just got to the point where we couldn't do any more. I've used white spray paint in a bathroom before and NOT had a similar problem (colored tile floor so I would have known if the white went everywhere). I hate Rustoleum. I hate the person who decided to market this paint for radiators. I hate that what was supposed to be a finishing touch turned into such a never-ending nightmare and has ruined all the pleasure my mom had been taking in her new bathroom. AARRGGHH!!
