Great idea
That's the same with me. I find the natural brown coating is also a nice way to protect the paint from bird poo. And no door dings since no one wants to park next to me in the parking lots 

I have this issue with brake dust. I was worried about ceramic ones cracking if I was towing but it doesn't seem to be a huge deal. I have Raybestos $100 pads from Fishers so not the cheapo ones. I have a set of Hawk pads waiting to go on next when these wear out . Hopefully that will be a while. I've thought seriously about trying to sell them but haven't done it yet. I figured if I could sell them I'd get ceramic ones next. I hate the brake dust and seems like I have to clean them once a week if I want them clean. It was like this with Cheapo Raybestos pads. Well $60 ones so not super cheap, then like this with OEM ones, then still like this with $100 Raybestos ones.
I just recently put some ceramic ones on a car to try out.

hmm here is an idea, just wash the damn things more than once a year
