BGDUMMY,
Aluminum Polished wheels (like Mickey Thompson, Weld, etc. ) you have to keep polishing them to keep them looking good(about once or twice a month where I live). The Aluminum wheel that has been Chrome plated (like the ones I got) will not rust, If you wash your truck a couple times a month and wax these wheel twice a year, that all you'll have to do to them.
