I used it one time only on my stock wheels ... now unfortunately I can't use in on my new black wheels ... after talking to a few detailers and HRE , they didn't not recommend to use it on my wheels ... this is such good product ! Your wheels stay clean for a long period of time and it will help to protect your wheels from the brake dust .
