Thanks for all the suggestions

I have used black sharpie in other places on my bike, even used the black sharpie to cover up some thread wear on the very edges of my seat just near the tank. It worked great.
My front fender is black but these aren't rub marks from a fork bag. They are more like irregular gouge marks in the paint. They don't take away from anything too much. Just kind of visible because of where they are located. (on top of the fender.) I may look around for a good decal or use the gothic black nail polish. I'm just wondering if black shoe polish might work? I still love my British Iron Speedy

Thanks again,
Bob
