I have a parts Strat that I put together last year and used Minwax tung oil finish on the neck. From what I have gathered, this finish is not necessarily a “true” tung oil finish and so I had a question. When assembling, I did not add a decal or anything to the headstock. I thought I would get used to it but it just looks bare to me. With that being said, my wife is an excellent artist and I would love for her to hand paint something in the area where a decal would normally be. Is there any paint that will go over this finish without issue? I am sure my best bet would be to test a few different paint types on some scrap wood but I wanted to see if anyone else had any experience with this.
