Sealing a surface-rusted metal roof

I have a big shed out back, approx. 600 sq. ft. The roof is metal and has some surface rust. No holes.

I would like to seal it, what should I use... normally I would use POR-15 on rusted metal but that would cost me a fortune for something this big.

What do you want the finished product to look like?

The cheapest/easiest thing to do would be to coat the roof with an asphalt based aluminum coating..... or you could use a solvent based primer and then coat with either regular aluminum paint or an oil base exterior paint in the color of your choice.

While sanding the rusty areas isn't imperitive, it will help to give a better job.
