My opinion - I have the SK and have used the metal polish on a lot of diamond plate, my kitchen appliances, my bike and anything I can find I love this stuff.
I would use metal polish 1 with the orange pad and then Metal polish #2 with a gray or red pad. You probably won't be able to use the pads for anything else, they will be black when your finished.
On a side note - your hull will be so shiny you can blind the fish
