I just bought a Squier VM Jazz neck with the black binding and inlays. The advertised neck on eBay said it was finished with vintage tint gloss, but this is not the case. It feels like bare wood. I talked to the seller and he offered me a refund if I return, or a partial refund if I keep it. I normally sand all my necks down on the back and tru oil them, but I've never done this to an actual fretboard. Will these block inlays take tru oil if i apply it to the fretboard as well? I believe they are plastic. Not 100% positive though. If not, I'll just return it. Thanks.
