Metal shed
 

We have a metal shed that is in great condition except that it has
rusted (even though we painted it when new!). What can we use to get
rid of the rust or prepare it for painting again? We also thought
about covering the shed (after fixing the rust problem) with vinyl
siding, what do you think?
Thanks!

I'm believer in POR-15 if you want to just paint the surface--

You will need to topcoat the surface to protect against UV.
