My understanding is that Fender used nitrocellulose lacquer on the headstocks of the guitars made in the 70s because they had troubles with the decals when they sprayed with poly. My understanding is that the rest of the neck was sprayed with polyurethane (correct me if I'm wrong). If they sprayed the face of the headstock with lacquer - would they have masked it off to do the rest of the neck? I'm just trying to figure out how I might replicate this process. Would the overspray screw up the front of the headstock? I assume that it would be somewhat of a mess because the sides and top of the headstock are so thin, you'd almost certainly have overspray. UNLESS - the side and top were all lacquer as well. Then you could just spray the back with the poly. Any information would be helpful. Thanks.
