I've been painting, which means I've been making a mess.  It's was a red mess.  And unfortunately my driveway is still bearing the marks of the project.  But the result was great, I think.
I took Miss A's old bed, which was formerly brass sprayed off white and sprayed it red.  It's now in the guest room.  
I used:
— 2 cans of Rustoleum's Red Spray Paint 
Here's what I learned:
— Rustoleum's Red is very red.  But looks great on metal.  It comes out shiny like a firetruck.
— Don't spray paint on a windy day.  Your surrounding area will end up pink (if you happen to be using red).
— You don't necessary have to rough up your surface to make the pain stick.  But it does help to avoid it chipping easily.  I didn't and we already have a few dings.
