Personally I don't get that aggressive with sanding and aluminum boat, especially if it's a work boat, or duck/fishing boat. I don't use vibrating or electric sanders on them either if they are riveted. The rivets can, and often do shake loose, causing it to develop leaks.
I sand over the loose areas, trying to get the flaky stuff off.
The other areas I lightly scuff. You can get aluminum primer and just spot prime the areas that need it.
I use Pettit Paint dead dull grass, so I'm not familiar with the other stuff. That's just my method.
