Everybody's entitled. I liked it. I think it worked for me.
This is what they say about the application:
Michelin Brake Dust Repellent is delivered to a clean wheel, allowed to wet the surface and wiped dry to a thin, streak-free film. When sprayed, a light foam will develop on the wheel and the foam will begin to break with an effervescent character. When the foam breaks, the repellent layer is forming to protect your wheels.
I like it over wheel wax because it is easy to apply. Spray it. Wipe it. Again, it doesn't repell everything, but it's easy and it will save you some effort in the long run. If you want to "wax" you wheels after every wash... go for it.
