Can the 10 ft. 5V Crimp Galvalume Steel 26-Gauge Roof Panel in Aluminum be painted with paint and primer?

Yes, Galvanized Roofing Panels can be painted 

Yes, Galvanized Roofing Panels can be painted or they can be special ordered in a pre-painted finish. This is one of the many benefits to metal roofing. Painting can be done to extend the life of the panels or simply to create a different look. As long as the old finish is well adhered to the metal, it will provide a great surface for a new coating. If you decide to paint we recommend using a good quality DTM (Direct To Metal) paint. To prepare the surface wipe down with (50/50) vinegar and water solution, this will remove any residue remaining from fabrication.
