As nice as it looks I think painting or using George's technique is the way to go.
I know they are selling a polishing product, but here is the info she mentioned during the forum. It is also posted on the Perfect Polish website under their tips and tricks section.
“Will repeated polishing remove the Alcad coating? Not according to Boeing. As a quality control measure Boeing polishes all of their exterior skin sections after forming using robotic polishers and Nuvite F-7. Apparently defects in the skin are easier to spot when polished. They once polished a section 370 times and the surface cladding (Alcad) was still there. Boeing says that polishing does not remove metal, it just “turns it over.”
Of course if the surface is badly corroded or has been sanded, the Alcad will be gone. But it will polish up nicely anyway.”
