I am modifying/refinishing my old Hamer Slammer P-bass clone. I removed the neck, and defretted it. Then, I filled the fret "trenches" with wood filler, sanded it down, and applyed 3 coats of polyurethane paint. My question is, how do I get that "new fretboard" shine? Where it feels smooth and almost glasslike? Also, I am removing the paint from the body and repainting it. How do I get that glasslike shine aside from painting it the way a car is painted? I plan on sanding off the original finish, spraying on a coat of primer, then a couple layers of black lacquer. How do I get that smooth, glassy shine? Thanks alot. I ll post pictures when I'm done.
