That's funny, I just finished posting to your other thread about drying that I use a blower and then the next thread I see is about blowers! Seems like you're thinking in the right direction to solve your other problem already!
I'm actually not familiar with air movers, so I can't really help except that I actually like the fact that my blower only hits a small area of the car. Reason being, I want to push the water off, and not dry the water on the car creating spots. If the air movers you speak of hit a larger surface area I'd imagine the air flow wouldn't be as forceful and possibly just dry more spots on the car than actually push the water off. Just my thoughts on the subject, but I'm sure someone who's actually familiar with air movers will chime in and clear this up.
