If your Goose wheels have ever been polished in the past, aluminum versions will still have some sheen left to them. Mag wheels will be a dull dull dull grey! Car I saw last weekend had three aluminum wheels and one mag on it! Looked odd!
If they are magnesium, then yes, they will require special procedures to redo them. If they are aluminum, then no.
Drop me an email and I can help you with this if you haven't done it already.
