Got a some questions about a finishing a Warmoth neck that I want to install on a Warmoth body that I just received. Here goes...

This how Warmoth's necks ship:

"All our necks are dipped in an oil based penetrating sealer which is compatible with virtually all secondary finishes. This provides enhanced stability; however, it is not adequate protection for playing. We strongly recommend you apply a hard finish to all Maple, Mahogany, and Koa necks."

The plan is to shoot the neck with a few coats of Behlen B104-1406 Stringed Instrument Lacquer Aerosol to give it the recommended hard finish. And although Behlen's instructions highly recommend the use of their B102-8000 Vinyl Sealer Aerosol product as a base coat, I was wondering if I really need this since Warmoth has already applied a sealer.

Secondly, since the neck has sat, should I sand it or rub it down with steel wool before applying the finish?

Lastly, the neck already fits very snugly in the body pocket, so should I be concerned about building up the overall thickness of the heel when I apply the finish? If the heel grows and has trouble fitting into the neck pocket, I suppose a little sanding of the pocket would solve the problem, but I figured I'd check in with you guys first, before I start.

Thanks in advance for any tips of suggestions that any of you might have.
No you won't have to apply the sealer first. That is to treat the raw wood before spraying the lacquer. Since the neck has already been dipped you shouldn't need to worry about that.

I would hit it with some steel wool at least before spraying. If it were me I'd go over the entire back of the neck with some 320 grit.

The neck pocket is your choice. You can finish the neck, and then do a bit of sanding if you need to get it to fit, or you can tape off the heel area that actually makes contact in the pocket. The choice is yours, although I prefer to have my heel finished as well.

Unless its a maple board remember to tape off the fretboard. Good luck dude.
I'll get some 320 and give a rub. The pocket surface that makes contact with the neck is unfinished, so I was thinking to leave that unfinished as well on the neck.

Many thanks for the advice. I'm going to shoot this neck today.....
