Or is it just that my finger board on my violin has been painted with some dodgy stuff?
I seem to have permanent black lnes on my fingers!!!
My fingertips always turn black while playing, and the paint has worn off my violin's fingerboard at the places most touched by my fingers. This tends to happen most strikingly on hot days (of which we have had too few lately). Probably a combination of sweaty fingertips and softened paint contribute.
Sometimes I also notice a metallic sheen on my fingertips too, but I think that was when I had a Dominant A string. Those are aluminium wound, so the soft metal probably wears off quickly. My A string didn't seem to last long before it broke.
