Two months ago I took each wire wheel off my car, cleaned them and chrome polished them.
Then I sprayed them with a couple of coats of the Anti Brake dust spray. (best to spray on when wheels are flat on the ground)
Two months later I can say that it works well. There is a very, very slight light film of brake dust on the front wheels, but hardly noticeable and nothing on the rears. (I have EBC pads that are less dust than stock, but they used to cover the front wheels with dust)
The product says it lasts a month or so but I think that is assuming you are washing the wheels so I think this will last all season.
I recommend it. This means I will only need to clean my wheels once year and that the cleaning will be a lot easier than it was in the past
