I tried reading up on it and i saw something about the coin trick rubbing against plastic and then something about using a magic eraser. These plastics arent faded it just has this like oxidation acid rain looking shit all over it, not sure what you would call it but it has the little black stuff on it from sitting outside for ever, i wouldnt think it would be necessary to try and sand them or something, was curious what a good way to remove this would be without scratching or fading the plastic all to hell, thanks.
