I have been using this and it works good. You get some build up in the corners, but I use a little compressed air and it all comes right off. Not like before when it starts getting into the clear coat. It is just a silane spray which makes the rim unreactive to break dust or other dirt particles. It is not a wax, it uses a silane compound (Decamethylcyclopentasiloxane) containing silicone with chemical functional groups on the silicone that have physical properties which make them either attract or repel certain particles. Waxes are composed of carbon and hydrogen chain molecules. I don't know if the silicone in the silane additive is phyically bonding to the clearcoat rim surface or it just dries and it is just sitting on top to coat it, but the other functional groups on this silicone molecule in the silane are free up and branch out to repel the dust/dirt particles. I am guessing it just coats the rim since it has a dry time and comes off when you wash the rim and then you have to reapply. I am a scientist and have use silanes to coat various particles to make them attract or repel other particles or fluids. Never thought to use them on a car rim.

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.
