Hmmm make sure the rim is really clean before applying. There is the wait time before driving, 1 hr. Maybe you need to wait longer for it to dry. Like I said I usually would drive the first time after washing and the front rims would be covered in dust. With this after applying and driving they are still clean accept in the deep corners it builds up, but I hit it with some compressed air and it come right off. After you wash you will have to re-apply. It won't last 4 week like it says. A week in between washing is good. Rims are much easier to clean.
