Note this is a picture of an old can type container, the polish now comes in a plastic bottle.
I do not use it anymore since I no longer own chrome rims but it worked quite well on the rims I had on my Z28 vert. It is a polish so it is abrasive so I would be careful using it on clear coated rims and soft metals like aluminum. The turtle wax worked well at removing both brake dust and rust on my rims. Applying the polish is easy and straight foreward, minimal effort is required when buffing the polish off. Making this product easy enough to use that it can be used every time you wash your vehicle. Overall I give it a thumbs up and would recommend it to the members on this site.
