I just wanted a quick fix , first I thought sand them a bit but Dutchie said all they really need is a wire brush,a clean with metho,dry and then a quick spray with cheap flat black,it'll come back but not for a while I hope.. Was going to plastidip them but because I had never used it before I didn't know the thickness of it, incase the hub rings wouldn't fit over the hub.. Happy with result, need to do the rears but ran out of time..
