Hello, I am new to working on guitars (basses) so my experience is limited to refinishing some solid body 4 stringers. I am trying to get advice about an alternative finish besides Tung or Tru-Oil. I have worked with both successfully, but I would like to re-do one of my basses in an oil finish of some kind that won't lay on top of the wood, but rather soak in and leave a mat finish. I keep hearing about a kind of oil/poly blend (Birdsong Guitars uses it, - so does Ibanez) that looks more like a Watco type finish but is a bit tougher. I have a walnut bodied fretless that I think would look and feel better in a mat, rather than a shiny clear finish. Any help would be appreciated! Thanks ...
