Mag & Alum Polish on Chrome?

[OneBlackFly]

According to the back label on my jar of Mag & Alum Polish, it is not recommended for chrome finishes. Why not? Thanks.

Automotive chrome is a hard, thin plating. Aluminum is a soft alloy. A polish that works well on one will not perform its best on the other.

We make a traditional Chrome Polish (part number 05212) and a new spray, All-Chrome (part number 05222).

I think you'd be happier with one of them on your chrome surface.
