Just got my lr4 serviced. Pads were gone complete. As a result my 22’’ Range Rover wheels are covered in brake dust and rust.... got the alloys powder coated black a few months back and they now look terrible. I have hot washed, applied tfr and also applied rust fall out. Still have residue especially on inside off rim - looks terrible ..... any ideas how to renovate guys...? also thinking of painting calibers to take away the old look. Any tips
