This polisher attachment certainly did the trick to get my chrome wheels restored like new. It's foamy and safe to use on expensive custom chrome wheels like mine. I would recommend it.
There are many similar products to this, however, THIS is the one you want. It's more expensive, but it's worth it IMO. I polished a set of four chrome wheels with it in about an hour and the results are perfect. My wheels look new again! It's also durable.
I was attempting to polish my rims but it seems that the big sponge would absorb the polish not allowing polish on the wheel. With that said seems to be well made.
I purchased this specifically to polish the metal wheel simulators on our class A motorhome. These are constantly exposed to water, dirt, brake dust, and other grime that leaves lots of fine scratches, scuffs, and spots. I used the wheel with a power drill and some Flitz metal polish. The extra RPMs from the power drill did not cause any shredding or flaking, and the results are great.
