I'm looking for something to finish my Korina 5 string with. I want to preserve the grey/black color of the wood. Most oil based finishes I've dealt with have that yellowing affect that I don't think will look good on this piece. Any thoughts on Minwax Polycrylic? I thought using a brush-on satin polycrylic smoothed with 0000 steel wool might give it a really natural look. I was planning on leaving to pores unfilled too. Any thoughts?
