It's actually hot outside, which I would think would make the paint dry faster. It is extremely bright, with zero wind. I got to spray paint the silver sides of the boards today, and I honestly don't think it was any more fun than the orange sides. I think things showed through the silver paint more, so I ended up using more of it.
I have nothing else to say about spray painting, because I've been saying everything there is to say for the past week. :D
