Finally got around to removing the poor quality ebay fake carbon spoiler. It was heavily oxidised and had very poor fitment.
Removing the glue residue was not fun at all even with goo off. Hand polished with what I had at home but desperately needs a proper machine polish to get rid of all the marring that was left behind. Much cleaner. Before and after below. In true bmw forum fanboy fashion there arnt any fake parts any more =p
