cos I know they should be muddy anyway, but the thing is I have a problem with my arch extenders. Some numpty has, at some point prior to me buyin the motor last year, waxed the motor and got wax onto the arch extenders. As they are the black ones and not colour coded they now look an absolute mess cos there is all this white stuff round the edge Does anyone know of a good product to get them looking nice and black again? I have been told back to black isnt that good so any other suggestions? (nice ones only please )
