Need to paint the bus

[blusubaru]

I confirmed the rumors with a state trooper last night. At least 51% of the bus needs to be a different color from the nationally registered "School Bus Yellow." So, I've got a little over 48 hours to paint the bus, and it's raining today. Tomorrow looks clear, so my question is, what's the best paint? We've decided on a gray color, and there's no time to sand. I was thinking of just getting a 5gal bucket of rust-olem, or some other type of exterior enamel paint and slap it on with rollers and brushes. It's going to get a good power-washing today in the driveway.
