Joe, years ago I painted on the aluminum sheeting used as chimney flashing.
I used spray paints and masking tape, which resulted in abstract designs.
You may want to make sure there is no oil film on the metal before you
paint by washing it with some type of solvent. I suppose if you roughened
the surface a bit with an abrasive, acrylic paint would probably work, if
you're not placing it outside.
