It MUST be all LACQUER in rattle cans. NAPA has the best IMO. Get some 400 grit, tack rag, primer (for lacquer) black lacquer and clear lacquer. Sand the headstock smooth (not to bare wood) dust and tack lightly. You don't want any dust. Shoot a few light coats of primer. Let it dry a few minutes then shoot a final heavier coat. I let primer dry 8 hours or overnight. Next, lightly sand (400) the primer, just enough to get a even smooth look, don't wanna sand through. Dust and tack well. Shoot your black, first coat light...see through. Let it flash dry a few minutes, and continue this way, building up thin coats, letting each coat flash. Lacquer is'nt meant to be shot in one heavy coat. You may shoot up to 10 coats this way, easily 1/2 hour or longer. Take your time. (I'm assuming everything was masked off... ) The 'final' coat may be a bit heavier for gloss off (wet). Let this dry..overnight if applying decals or 5 minutes if not and you'll shoot clear. Assuming it's a hot day, longer wait if not ideal (I'm in Hawaii btw, so we have good days, except this mega rain storm right now ) If moving on to clear, again, start light and build slowly, 10 coats more or less. Last coat can be heavier for gloss off. Let this dry a day or longer. Remove all masking after an hour, slowly. The gloss may be fine and left as is, but can be buffed out using the methods above. Good luck.
