I have an Endura that has the black FRN that kind of look dark blue and I want to dye them OD green on the texturing and a darker black on the flats and on the border. How would I go about doing this? I assume I would have to lighten up the current color and I heard dye remover works for this. Is this true? And what can I do to protect one part of the handle while the other is being dyed? Thanks in advanced?
