It's all about marketing bullet points and the susceptibility of guitarists.
In the end, nitrocellulose is a crap finish that was tossed by the automotive industry six or seven decades ago. Fender (and others) used it back when because it was cheap to buy it as leftovers from the local car manufacturers. They still push it because there are people who want to be just like their nearly dead guitar heros.
I don’t care about the guitar hero’s actually. I just want a reissue to age and wear as close as possible to the model it’s supposed to be emulating. I can’t afford a real one so this is the next best thing. Is there something wrong with that? This topic goes back over 10 years on this site alone, so there’s lots more to it than trying to copy some dead rock legend.
