LOL! I got the idea from you initially in the SA wasteland iirc.
I did 3 light coats of the Metalcast Ground Coat (silver), then 2 light coats of blue followed by a heavier coat of blue as instructed on the can. Having looked at them today they look better (a little lighter) in more sunlight like the LHR photo with wheel off (those photos taken yesterday as the sun went down). Like the Mrs said, had I tried to match the nuts, it would have been too much of the light blue and take too much away from the wheels. I didn't dremel anything, just cleaned it all up and then masked off with tape and newspaper.
I've seen that gb, those gold passivated rotors look pretty tasty.....
