A family member has told me to sand down the ball of my Towbar before I tow the caravan, because the coating on the Towbar makes the stabiliser pads on the alko/winterhoff/ bpw hitches inefective???
Is this correct? Would rather get another opinion before messing with something that was only fitted 2 weeks ago!!!
Yep. Use fine emrey paper and finish off with spray brake cleaner and clean cloth. Then every so often do the same again, stops any squeaking from the stabiliser pads.
The tow bar is the part that is bolted to the vehicle chassis but the part you are referring to is the tow ball which if your caravan has a stabiliser hitch then yes the towball needs to be completely free of paint, grease and any other particles for the internal friction pads to work effectively. However, when you talk about sanding down it doesn't require a rough grade sandpaper but the smoothest you can find.
Another tip is to spray the inside of the hitch with a brake and clutch cleaner spray which is specifically designed to clean brake shoes, brake pads and clutch linings etc. which is the same material as the hitch friction pads. The brand I prefer to is Holts as the can can be used upside down which is ideal for this type of application.

It's obvious you have not done any research on this issue but have a look at the facts in the link which comes direct from AL-KO. On the right are questions and answers and the very last question (I have a new AL-KO towball - do I need to take the paint off) confirms what the OP has asked.

You have not had any issues YET.
There is a reason Alko tell you to remove the paint from the towball and it isn't because they have shares in wire wool. Do hope you only tug with you in the car.
Once the protective paint is removed use a tow ball cover to keep the ball clean and as dry as possible because it will now rust. You will need to wipe this surface rust off before each use, the same fine emery or wire wool will suffice.

The towballs are dipped in protective paint after production for two purposes. Firstly it protects the surface to stop any rusting and secondly it cuts down on cost as each and every towball that has to be independently covered and then removed reduces production time thus increasing the cost. Besides, it's a no brainer really as I don't think any customer would be happy purchasing a brand new part that is covered in surface rust.

What paint my tow balls have always been chrome vanadium or stainless steel and always cleaned before and after use then covered .
Yes my last towball was a fixed flange Alko which was chrome. Not seen a SS one though.
