Dennis, somewhere months ago, one of the guys on here took a 17' proteam and buffed it until it looked like chrome! Really, like a mirror. I would look into what compund he used! LOL, Maybe not go that excessive, but WOW, it did look sharp afterwards. I can only imagine that a finish like that would be so slick, that very little could cling to it in the water. Almost easier to maintain. I could be way off. When I had an aluminum boat, I just used the Wal-Mart stuff. Boat cleaner by Star-Brite. Worked good for me.
