If simply faded, it has possibly protected the machine-turned finish and simply need stripping and recoating in very diluted clear yellow. Easier said than done, the colour is hard to get right without overdoing it and scrubbing the surface will effective ruin the finish. If you had a lighter panel in the correct 'gold' then it would also serve as a sample to match. RC will know if it can be saved, as is, if he is still doing any.
