That's what I used. I went to a paint store (an actual store that only sells paint, not the paint counter at home depot). I asked them what I could use to paint 30 year old sheet metal that still has a pretty good base coat from the manufacturer, but I wanted to change the color. They recommended a latex/acrylic house paint.
I quickly hit every surface with a power sander, then wiped the dust off with acetone. The acetone really brought out the original yellow, and made it look less faded. I used foam rollers. I could still see yellow through the first coat. It took about three coats before the color I bought really started to show.
I'd say it took a little north of 3 gallons to paint my 26' bus. It's still relatively fresh and I still have touchups. I've only got 1,100 miles and 1 month on the paint job.
