Ceramic Coatings Detailing Spray
I've been using ceramic coatings on my car and my plane and have been very pleased. Almost all of the major car care manufacturers (i.e. Turtle Wax, Mothers, Meguires, Griots, etc) make some version of a ceramic coating. If you go with a ceramic coating to begin with, then you can use whatever detailing spray that manufacturer makes to go with their ceramic line of products.
I've been using the Turtle Wax line of ceramic products since they came out with them a couple years ago. It's very slick, easy to apply, and the detailing spray does a good job of debugging the leading edges. And the gloss really shines. But my plane is painted, so I don't know if that helps the OP much.
Most of the ceramic coating manufacturers state you can use their products on polished aluminum wheels, but I don't know if you can use it on Alclad. Simple Green makes a cleaner specifically for aircraft, as I think there may have been an issue years ago with standard Simple Green etching aluminum. I've used the aviation Simple Green as well, but it doesn't leave as slick of a surface as the other cleaners do.
