Side note on brake dust...
I dunno if you guys know of this product called P21S *gel*...
This stuff has been recently released in a past few years?
I came across this stuff on YouTube.

There's a bunch of them vids on YouTube if you do a search (i.e. "p21s gel").
Brake dust should not be a problem anymore.
