ukSteve;
All I can offer is what I've been told when I was looking at repainting my aluminum awing covers.
Aluminum needs a special prep or a paint that contains the chemical to prep it and cover it at the same time, and it is not cheap. It seems normal paints will not adhere well to aluminum. It seems the metal needs to be etched in some way to have paint adhere.
I don't have the thread on hand here but you might want to search the forums.
Just google the following "aluminum painting techniques" for some basics
