What paint to use on a box section tin roof?

[imagedude]

My tin roof is going rusty and would benefit from an application of a protective coating. It is a box section in roof i.e. thin steel covered in a polyester coating. The coating has long since disappeared. What would be a suitable paint to use on this roof?

Not used it myself but Bedec Barn paint is suitable I believe ....
Or bituminous paint perhaps ?

How practical is it to try and seal where the plastic coating is lifting on the ends of plastic coated steel box profile sheets ?

Jotun 90 epoxy paint.
Will last longer than galv.
The ideal way to apply is with a high pressure airless spray but can be brushed or rollered.
