Well anyone who hasn't purchased one of your plaques is missing out. Since I purchased 2 of the plaques (one was engraved off center), I used one of the plaques and made a framed picture set of my car. I had some nice 4x6 photos of my car so I framed them and put the engraved plaque in the corner. Turned out great.

As for the brake dust issue, have you tried the Orange Degreaser Wipes made by greased lightning? They aren't $1/container, but I'm wondering if they'd do the job...
