Refinishing a painted headstock

I have a great MIM neck. The rosewood is a gorgeous light brown, almost like a chocolate. My problem is that the headstock is painted yellow. What is the best way to remove the yellow and just give it a natural gloss finish? I'm only doing the "front" of the headstock. I would like to reapply a decal as well.

I do not have any equipment to spray a finish, so a finish that can be rubbed on is preferable. Thanks!

Safest but not the fastest way would probably be block sanding it. That way theres no chance of damaging the finish on the edges like if you were to use a stripper or heat gun. Then apply a few coats of True-oil.

OK. What about a waterside decal? Does that go on the bare wood before the tru oil?

Get a few coats of oil on then sand it smooth and apply the decal over that. If it's not smooth you can end up with air bubbles. You can then just leave the decal as is or apply a few more coats of oil over it to protect it from getting scratched off.

What about tung oil?

This is the neck

Forgot to attach!

Is that a solid color or can you still see the grain?

Its solid. The rest of the neck is clear maple.
