My in-laws would like me to detail their pontoon boat before they winterize it and put it away for the season. It doesn't need much, just a good cleaning. I primarily detail vehicles, but I wanted to do this for them. I would like to lightly polish the pontoons and need to get a metal polish that would be sufficient for both cases. Since I don't want to purchase a product for a one-time detail would McKee's Fast Metal polish work or could someone recommend another alternative that will get great results for both use cases?

I appreciate any recommendations.
