After seeing this thread I got some and tried it out on the x3. After one week, wheels look freshly washed. Even wiping my finger across the spokes comes back clean with no residue. Liking it so far. Have to figure out how to best apply it. First time I used almost half the can. Will try smaller amount next time.
