I have a screen room with aluminum framework. One piece of the aluminum has

Thanks,

Your aluminium is/was anodised to make it corrosion resistant. Bird/
any other crap is quite corrosive & may well take it off.
Paint doesn't take well to aluminium or zinc. You need get any crap
off first with a wire brush & then you need to apply etch primer
paint. This is slightly acidic and bonds well to the metal. You can
then apply more or less any exterior grade paint subject to what it
says on the primer can.
