So I bought a sad condition PS4 Limited Edition Batman Arkham knight. The shell is not in great condition and the inside needed extensive cleaning as you would imagine. I got it at a steal of a deal but want to make it "whole again". I will be eventually repainting the plastic shell the exact Steel grey again but the batman hard drive cover is badly scratched and somehow stained which I am unable to clean up. Looking for options to restore or replace this piece, thanks again!
