At first I was floored about the brake dust on my E91. Nothing off the shelf worked, it was like my second job keeping clean.

In a roundabout way, I came across this:

My buddy lost his job and started selling it. Hands down, amazing. After you use this stuff your fingers will feel like they are coated in slippery teflon. I like what it does to the car, but its even better on the rims.

Get'em clean, spray on and let haze, then buff off. I now just hose down my rims and dry normal. Every so often I need to hit it with a soft brush, but I'm telling you the dust just flys off, its too slippery.

I use the Luster about 4x per year. Only concern is any of this stuff on the brake itself will be bad, so I'm careful when applying.
