Hello, I've always thought it would be nice to reproduce Mick Ronson's Tele, which to the best of my determination is probably a circa 1969 or so in Lake Placid Blue. (It has a rosewood veneer board with a truss rod plug.) Being that such a guitar's body would have been urethane finished, it theoretically makes a body quite a bit easier and cheaper to track down than a replica built based on a nitro finished year. However, I have always noticed that even the older urethane finished Fenders experience wearthrough eventually. For instance, look at this '69 photo that I pinched from a completed Reverb listing: That's definitely not something that would happen with a "modern" urethane finished body. So how do I recreate these late '60s custom colors so that they naturally wear this way over time? What was different about the old urethane that Fender used? Is that exact material still available today? Thank you.
