I have just changed my towcar and had a new fixed Witter 50mm towball fitted. I noticed that it was all black -  previous towballs I have had have been 'clean' metal. I seem to remember reading somewhere that if a towball comes ready painted, the paint must
be removed using  fine emery paper before it can be used with the AKS 3004 friction stabiliser. Has anyone come across this before and are there any recommendations?
