Hello to everyone, I have some doubts regarding my vintage 1975 Fender Jazz Bass painting. Since it was a strange black painting, I supposed that it was repainted over its natural colour , so I brought the bass to my luthier. He used a light solver and, since the black started to go away very easily, he jumped to the conclusion that the bass had been repainted, also because Fender stopped using Nitro paintings before 1975 and a Poly finish would have not come off easily with that solvent. Below there are some photos of before and after the solvent. You would say "All ok!", but then here come all my doubts, I've found THIS: 1975 Fender Jazz Bass, Black The paint is black as it was mine, but I can't see effectively if it's a nitro or a poly painting. Thinking about the year, it should be poly, but the wear and age signs are very similar to my black body. What do you think about it? I'm afraid I did a mistake in taking it to my luthier for un-paint it if the paint was original. Looking forward to your replies, hope you can help me to understand the mistery Thanks to all in advance.
