Wonderful instrument, use it mostly in fretless mode with Roli’s Equator.
There seems to be some sort of paint over the rubber fretboard that’s flaking off. I don’t like the inconsistency in feel between the bare rubber and the “painted”.
The advice I saw somewhere in this forum is to use mineral oil, but I don’t like the fretboard to be oily. Any other substances? Talcum powder, new layer of spray paint? Plasti Dip Spray? What’s the material anyway, urethane rubber?
