Repainting a cast-aluminum porch bench
I have a cast-aluminum(my wife says, I think its iron), porch bench, it is slightly rusted after 12 years, and the paint, which is baked enamel is starting to crack, I want to repaint it, but have NO CLUE HOW TO EVEN BEGIN, any help would be great, thanks.

If its rusted (red)...it's not aluminum.....aluminum corrodes (whitish).
If I was doing it, I'd use a wire wheel on a drill to get the loose stuff off and remove most of the rust. Clean everything well with a Metal Prep/ Prep and Etch (available from a paint dept or store...follow directions), clean well with paint thinner or mineral spirits. Follow up with a rust preventative primer and finish coats or a hammered metal finish that doesn't require a primer.

Vic's advice is solid 
The only thing I would add is if 1 of the coats [primer or finish] can be brushed on, you'll have a thicker coat which means the paint job should last longer. The paint in aerosol cans is drastically reduced so that it will spray. That makes it harder to get a thick film of paint/primer to protect the substrate.
