I'm working on defretting my old Ibanez to give it a new life. After much online research, I defretted the neck and got quite a bit of chipping around the frets (oops). I brought the neck into a hardware store so I could try to find a wood putty to match the neck color to fill in the chips. They told me they didn't think that wood putty would stick in such small cracks (they were talking about the chips on the neck, which are pretty small, but also about the holes where the frets were!), especially with the tung oil finish I was thinking of using. I thought these guys were kinda full of crap, but just to check...has anyone had problems with wood putty not holding up their frets (with tung oil or not)?
