I recently removed the seats on my WRX and accidentally scratched the door plastic with one of the seat frame ends. The scratch was not terribly deep but left the typical light color change of most plastics when scratched or deformed. Is there any way to chemically or mechanically remove, repair, mask etc this kind of scratch? I don't want to paint the interior but open to suggestions. I can live with the scratch if it were less obvious. Thanks for you advice.
