I use the maroon 7447 pads for that sort of thing. They hold up well to the acid etch (unlike steel wool).
Ed: Aluminum can be challenging to paint. It definitely needs to be roughed up to give the paint something to bite into, but it also needs to be scrupulously clean. That's what the metal prep does. I normally apply primer/filler to the bare metal, sanding between coats until the scratches are filled, then paint.
