My spoiler has been like this since I bought it and I now need to do something about it. I have tried Kiwi shoe polish, Autoglym bumper care and some other back to black type products and whilst they make it darker none remove the streaks.
Was thinking maybe a light sand just to take the top layer off but a bit wary of this. Or the heat gun method but still not sure if this will remove the streaks.
Any ideas welcome. Thanks
