Yeah! What is to stop me from oiling over the Decal on the headstock? Tung oil should bond to the polyurethane or acrylic black face and not eat the decal? Did I mention I tried black transfast dye and I could not get the mahogany to look Black, it just became darker mahogany.

So you use acrylic to spray like "Krylon" or similar. I am afraid I am stuck with whatever I can find in a big box home store place in my neighborhood.
