I love the gloss finish on my MIM Classic Series necks. I'm getting a Korean birdseye maple neck from a Lite Ash Strat soon. It's has a satin finish and I'm wondering if I can simply spray it with a suitable gloss poly or lacquer finish without sanding it down to wood. I was thinking I would light sand the existing finish with 400 or 800 grit then maybe 4, 5 coats of clear. Might give the fret ends a polishing while I'm at it as well. Would that work or must I strip down to bare wood? Can I spray Reranch lacquer over the existing polyurethane satin? Any help much appreciate. Thanks!
