So I'm making a Tele for the other guitarist in our band; he wanted a replica of George's rosewood Tele so I meticulously stained the mahogany body and maple neck with water-based General Finishes "Cabernet" stain. Lookin' good so far. So he wants to have a friend hand-paint his name or whatever on the headstock and then send it back to me to clear-coat and assemble. I'm used to using wipe-on Poly on bodies and necks & have had very good success with it. Whatever artwork the gal does, I'm gonna have her paint a sample on scrap before I complete this project. So the questions are: Should I put a coat of poly on top of the stain before she paints it? What kind of paint should she optimally use on her end? Are there any kinds of paint she should specifically avoid when she does her thing? And assuming she uses enamel or acrylic artist paints, would we have a problem if I put another coat or two of wipe-on poly on top of it? (Like I said, gonna scrap-test anyway.) Or should I use spray lacquer? Whaddya think??
