Well I have a Disco 2 with running boards covered in some kind of rubber/plastic top liner. For ages when I wear shorts people have commented about the black stuff on the back of my calfs. It was not too concerned because when I have my annual bath I washed it off.
Now that I am part retired I decided to fix this and found the black stuff was coming from the surface of these running board covers. It was not road dirt it was from the covers themselves.
So I washed the covers let them dry and painted them with Screwfix no nonsense floor varnish. It has worked a treat. If others have this issue give it a go. I had the floor varnish so no cost involved.
This will actually save me money as I can now switch my bath to bi annual
