Thanks for the help, guys.
I went ahead last night and masked off the headstock and started spraying nitro. Seems I had just enough left in a Preval to knock out the job so why not? Coat of sealer last night, 3 coats this morning, more coats over the next couple of days...figgered I put this much work into it, what's a couple more weeks wait, huh?
Thanks again for all the help. Seems I can't make up my mind, here. Sprayed nitro, sanded through, took nitro off and tried Tru-Oil, took Tru-Oil off headstock and went back with nitro... wish I'd just resprayed nitro on the headsock when I sanded through, now! Oh, well, live and learn. That's where experience comes from, right?
Can't wait to try out the Tru-Oil neck. Looks and feels great already! (OK, it's still a little sticky, but I see the potential!)
