I'm going to be defretting a bass. I'd like to do this as economically as possible. I know that I could buy an already fretless neck but I've got a nice neck right now. I'm going to be buying a radiused sanding block and I have a full set of Micro Mesh pads. Could I realistically use a 4" sanding block and the Micro Mesh pads to sand the fingerboard level? The frets are coming out pretty easily.
